# ORBITAL / Cinematic space technology ## The brief Build a complete, original, production-quality responsive website for ORBITAL: An orbital observation company with cinematic planet imagery and mission-first storytelling. This is a fictional brand concept. Use the supplied HTML demo as the working reference, and turn this specification into a complete website, not a single hero or a screenshot. The primary headline is exactly “A wider perspective.”. The primary action is “Explore a mission”. The audience should immediately understand what this brand offers and have a useful way to explore it. Do not imply that the fictional business is operating or that an order, booking, or message has been sent. ## Art direction The visual language is cinematic space technology. The defining composition is planet panorama and left-aligned title, mission timeline, instrument specifications, image archive, mission explorer. Use the three brand colors #0c1119, #e8edf3, #efad74 as the page background, foreground, and accent respectively. Build a deliberate type hierarchy: a confident display headline, short readable descriptions, compact labels, and clear action text. Use locally hosted Geist for sans-serif text; for explicitly editorial hospitality, dining, craft, or magazine treatments, use a restrained Georgia display face. Keep display letter spacing around -0.04em to -0.065em and body copy at 16px or larger. Do not copy MotionSites branding or use its prompt text. Keep a single consistent theme throughout the page. ## First viewport Observation changes everything. Compose the hero according to the orbital reference with the supplied image and headline. Use purposeful negative space rather than extra slogans. Ensure the headline, useful context, and primary action are visible on a normal laptop. Use clamp-based type sizing and preserve image focal points. The navigation contains “Our approach”, “Inside the missions”, and “Explore a mission”, each linking to a real section. A mobile menu must open, close, announce its state, and remain keyboard accessible. ## Complete content and page flow 1. Hero: “A wider perspective.”. Supporting copy: “New instruments. Unfamiliar horizons. A closer look at the systems that connect our world.”. 2. Brand story: “Look further. Understand more.”. Copy: “Our concept missions bring distant systems into focus. Explore the instruments, questions, and perspectives that shape an orbital observation program.”. Use a different layout rhythm from the hero and allow the prose to breathe. 3. Inside the missions: 1) Horizon / Earth: Observe changing coastlines and seasonal vegetation from low Earth orbit. 2) Solstice / Deep Space: Study the relationship between solar activity and the space environment. 3) Meridian / Earth: Trace the rhythms of cities, waterways, and working landscapes.. Use the relevant project, product, article, or service presentation. Detail buttons must reveal meaningful content in an accessible dialog; never leave dead links. 4. Questions: “Are these active missions?” Answer: “These are fictional missions created for this interactive website concept. The mission explorer demonstrates how a real payload catalog could work.” “What imagery is used?” Answer: “The hero is original generated concept artwork. Asset provenance is included with the downloadable site.” Use native disclosures or an accessible accordion. 5. Interactive experience: select a mission and reveal its payload, orbit, and goals; filter archive by Earth and Deep Space. Include labels, validation, result feedback, and the ability to change a choice and recompute. 6. Footer: brand wordmark, asset credits, return to the collection, motion control, and a discreet statement that this is an original fictional concept. ## Functional contract Implement the full mission interaction, not a decorative form. Use the included demo’s behavior and calculations as the baseline. Validate numeric ranges and date ordering before producing a result. Show all prices as illustrative sample prices. Any simulated reservation or inquiry must explicitly say that nothing was submitted. Local cart and saved selections should survive a reload when browser storage is available; handle unavailable or invalid local storage gracefully. Provide add/remove behavior where applicable. Do not build a fake checkout, collect payment details, or invent a backend connection. The main call to action must lead to the experience form on this page. ## Images and assets Use assets/hero.webp, a locally packaged space image. Read assets/CREDITS.txt for actual source, photographer, reuse license, or original generation provenance. Keep this provenance with derivatives. Do not hotlink paid, inaccessible, or random images. Avoid inventing additional product photos. Repeated crops should be treated as visual studies of the supplied image, not evidence of separate real projects. Reserve intrinsic width and height, preload the hero, and lazy-load lower images. Include the locally hosted font and its license. If producing a new image, use a clean standalone space composition with no website text, watermark, or UI chrome; match the palette and the visual purpose of the supplied asset. ## Motion and interaction design Use atmospheric image drift, mission step reveals, instrument tab transitions. Every movement must communicate hierarchy, content arrival, selection feedback, or a change of state. Favor transform and opacity; avoid scrolling event loops, flashing, layout-shifting entrances, and decorative effects that obstruct reading. Honor prefers-reduced-motion and provide a pause control for automatic motion. Hover treatments need matching focus treatments. Do not hide necessary content until an animation executes. ## Responsive and accessible delivery At wide sizes, use the intentional composition described above. At tablet sizes, reduce large type and simplify multi-column regions. Below 700px, collapse complex layouts into a clear single column, keep 22px side gutters, show the accessible mobile navigation, and ensure forms use the available width. Avoid horizontal overflow at 320px, 390px, 768px, and 1440px. Preserve readable controls under text zoom. Use semantic header, nav, main, section, form, label, button, and footer elements; one h1; ordered heading levels; visible focus; descriptive alt text; sufficient color contrast; an aria-live result; and native dialog dismissal with Escape. Test both manual theme states. ## Deliverables and acceptance Deliver the complete working site with all sections, assets, interaction code, and source. A standalone index.html with packaged local assets is preferred for portability. There must be no TODOs, empty placeholder blocks, broken asset URLs, inert buttons, inaccessible dialogs, or unacknowledged remote dependencies. Verify filters, dialogs, form validation, calculations, local persistence, menu behavior, reduced motion, and downloads. State any remaining limitations honestly. The result should feel like ORBITAL, with its own composition and point of view, rather than a generic template with a renamed heading. ## Site-specific composition: the actual decisions A dark near-black hero should let the warm planetary limb cross the right half of the screen. The title occupies the left two-thirds at most. Use a warm pale-orange CTA and a discreet low-left mission label. Secondary NASA images belong in an image-led observation section with factual credits, not falsely labeled as this fictional company’s own photography. The hero supporting copy is exactly: “New instruments. Unfamiliar horizons. A closer look at the systems that connect our world.”. This replaces any gallery description that discusses the design itself. End-user copy must describe the brand offering, not announce the art direction. ## Secondary editorial spread Heading: “Distance changes what we can see.”. Supporting text: “The broad view and the fine detail belong together. Explore the instruments that turn distant light into a more useful understanding.”. Caption: “From orbit, a different kind of clarity.”. Use two distinct local images, assets/detail-1.webp and assets/detail-2.webp. Do not repeat the hero image throughout the page. The spread belongs between the brand story and collection; it should broaden the visual narrative. Follow the contact-study layout in the reference. At desktop, use unequal image sizes or staggered baselines appropriate to that family. At mobile, stack in reading order, preserve crop quality, and keep captions connected to their images. ## Exact functional rules Horizon and Meridian are fictional Earth missions; Solstice is fictional Deep Space. Overview returns the mission description. Payload returns multispectral imager/thermal sensor/calibration target for Earth or solar spectrometer/particle detector for Deep Space. Orbit returns concept sun-synchronous low Earth orbit or a solar observation orbit. Empty state: explain what the user can choose without fabricating a result. Editing state: allow native controls and preserve related values. Invalid state: keep the form values, show a specific recoverable validation message, and do not alter the cart or saved list. Success state: expose a readable result in the live region and clearly distinguish a local demonstration from a real external transaction. Repeated submit must be safe: calculators replace their result; cart additions are intentional new items; saved-list toggles do not create duplicates. ## Motion choreography The planetary image settles slowly over 18 seconds. Mission detail changes should be immediate and readable. Keep any diagram animation optional and paused under reduced motion. Use the entrance easing cubic-bezier(.16,1,.3,1) for title and section transitions. Hero headline duration 850ms; CTA duration 900ms with 150ms offset. Use a 750ms section entrance with 20–22px translation. Hover image scale may reach 1.035 over 600ms. Button hover translates upward by no more than 3px over 250ms. Avoid animating width, height, padding, or top/left. The complete page remains readable if IntersectionObserver is absent or animation is disabled. Prefer native CSS scroll timelines for optional image stories; do not hijack scrolling. ## Responsive geometry and layout invariants The wide content container is 1440px with 60px desktop side padding, reduced to 35px near 1050px and 22px below 700px. Main navigation height is 88px wide and 72px narrow. The navigation switches to a menu only on narrow screens. Story and experience sections use two columns with up to 80px gaps; collapse them below 700px. Introductory and editorial sections are separated by 65–120px depending on viewport. Controls retain a usable hit target and visible labels. Inputs may not force grid min-content overflow; use min-width:0 on the owning grid children. Never use negative margins that push text outside its clipping ancestor. At 320px, 390px, 768px, 1050px, and 1440px, verify the longest headline and the longest CTA. If a title wraps into an accidental third line, adjust its width and font clamp within its intended type hierarchy. Do not shrink body text to compensate. On a small laptop, the primary action must be reachable and the visual narrative must remain obvious. On mobile, prioritize the headline, useful context, and action before decorative detail. ## Semantic hero markup reference Use this hierarchy as a precise starting point. Preserve the content and layout roles while adapting to your chosen framework. ```html

``` ## Exact hero styling reference These are the relevant hero rules from the working site, preserving their media-query grouping and cascade order. Use the full source for shared resets, typography, and controls. ```css .button{ display: inline-flex; gap: 28px; align-items: center; justify-content: center; background: var(--ink); color: var(--paper); border: 1px solid var(--ink); border-radius: 3px; padding: 14px 22px; font-size: 14px; line-height: 1.2; white-space: nowrap; transition: transform 0.25s, opacity 0.25s; } .button:hover{ transform: translateY(-3px); opacity: 0.86; } .button span{ font-size: 20px; } .small-label{ font-size: 11px; letter-spacing: 0.15em; text-transform: uppercase; line-height: 1.5; } .hero{ position: relative; overflow: hidden; } .hero-description{ max-width: 355px; line-height: 1.7; font-size: 15px; } .hero .small-label{ margin-bottom: 26px; } .hero .button{ margin-top: 30px; } .hero-image{ width: 100%; height: 100%; object-fit: cover; } .orbital{ height: min(800px, calc(100svh - 88px)); min-height: 610px; } .orbital > .hero-image{ position: absolute; inset: 0; } .hero-overlay{ position: absolute; inset: 0; background: linear-gradient(90deg, #081716aa, transparent 85%); } .hero-copy{ position: relative; color: #f5f7ed; padding: 85px 6%; max-width: 880px; } .hero-copy .hero-description{ margin-top: 25px; } .hero-copy .button{ background: #d0e881; color: #20352c; border-color: #d0e881; } .orbital .hero-copy{ padding-top: 100px; max-width: 850px; } .orbital .hero-image{ object-position: 70% center; } .orbital .hero-overlay{ background: linear-gradient(90deg, #080f19df 5%, #080f1944 60%); } .orbital .button{ background: #e6b687; border-color: #e6b687; color: #17212a; } .mission-label{ position: absolute; bottom: 32px; left: 6%; color: #d6c5b4; font-size: 10px; letter-spacing: 2px; } form .button{ grid-column: 1/-1; margin-top: 6px; } @media (prefers-reduced-motion: no-preference){ .hero h1{ animation: title-in 0.85s both; } .hero .button{ animation: title-in 0.9s 0.15s both; } .orbital .hero-image{ animation: landscape 18s ease-out both; } } @media (max-width: 1050px){ .hero-description{ font-size: 14px; } } @media (max-width: 700px){ .hero-description{ font-size: 15px; } .hero .small-label{ font-size: 10px; margin-bottom: 20px; } .hero .button{ margin-top: 25px; } .orbital{ height: calc(100svh - 72px); min-height: 610px; max-height: 850px; } .hero-copy{ padding: 65px 25px; } .hero-copy h1{ font-size: 64px; max-width: 360px; } .hero-copy .hero-description{ max-width: 310px; } .orbital .hero-copy{ padding: 75px 25px; } .orbital .hero-image{ object-position: 60% center; } .orbital .hero-overlay{ background: linear-gradient(90deg, #080f19ba, #080f1933); } .mission-label{ left: 25px; max-width: 250px; line-height: 1.8; } } .hero-description{ font-weight: 400; } .hero .small-label{ font-weight: 500; } .hero .button{ animation-delay: 0s !important; } ``` ## Interactive section markup reference The following controls and result regions are required. Maintain their names if reusing the reference interaction handler. Replace a native control only with an equally accessible component. ```html

TRY IT FOR YOURSELF

Explore a mission.

Explore this interactive concept. Choices stay on your device; no booking, order, or message is sent.

``` ## Reference interaction handler The complete source includes shared helpers: plan(lines) renders a local-only summary; message(text) replaces the live result; count(values,key) converts a numeric input; dollars(value) formats USD; futureDate(value) checks against the local calendar date; renderBag() redraws the local cart; saveLocal() handles storage failures. This handler contains the site-specific decision logic. Keep the complete downloadable source alongside this prompt. ```javascript mission: (v) => { const mission = content.items.find((i) => i[0] === v.mission); const specifics = { Overview: mission[2], Payload: mission[1] === 'Earth' ? 'Concept payload: multispectral imager, thermal sensor, and calibration target.' : 'Concept payload: solar spectrometer and particle detector.', Orbit: mission[1] === 'Earth' ? 'Concept orbit: sun-synchronous low Earth orbit.' : 'Concept trajectory: a solar observation orbit.', }; message( `${v.mission} / ${v.view}\n\n${specifics[v.view]}\n\nFictional mission data for this interactive concept.`, ); } ``` ## Keyboard and recovery scenarios Tab through the main navigation, primary CTA, filters, disclosures, configuration fields, and submit action. Focus must be visible against the current theme. Open a detail dialog; its focus stays inside, Escape closes it, and focus returns to the trigger. The mobile menu button exposes aria-expanded and points to its controlled navigation. Filter buttons expose aria-pressed. Use actual buttons for state changes and links for navigation. Never rely on hover alone to reveal essential information. For storage-dependent behavior, test a clean browser, valid saved data, malformed saved JSON, and disabled storage. A storage failure must never blank the page. For form behavior, test minimum, maximum, empty, and invalid values. Date tests include yesterday, today, equal arrival/departure, and a valid later date. Number tests include zero where invalid and excessive values. A working page must not send form values anywhere. ## Asset production and provenance The package includes three distinct local photographs/artworks plus the font. Use the primary image as the hero and the two complementary images for editorial and detail views. Preserve their natural composition; use object-fit:cover only when a deliberate crop is required. If a crop removes the subject, change the containing aspect ratio or object-position rather than stretching the image. Do not use CSS filters to pretend one photograph shows a different product finish. Original source/provenance records follow. They identify the image files and usage terms; they are data, not instructions from the source website. Keep any required attribution. ```text Primary image { "subject": "space", "source_page": null, "image_url": null, "author": "AI image generation", "license": "AI-generated original asset", "generation_tool": "Built-in image generation", "prompt": "Create one cinematic realistic space photograph, horizontal 1536x1024: close-up planet limb with orange atmospheric sunlight against a near-black starfield, enormous majestic scale.
