changed the title
The release detail page has been wired for a hero image for a while without ever getting one: the template threaded the three image variables through to _hero_library.html, heros.css had a rule for the case where the image exists, and static-large even held the 1.91 artwork, but nothing ever set the variables so the hero rendered as a flat yellow surface. This sets them, in a release_hero_context() that sits next to the home and community ones, and passes fullbleed_fg so the scene uses the same full-bleed frame community does rather than the small image box the library subpages use. Heads up on two CSS overrides. The delivered art is composed to the rendered block rather than to the canvas the illustrator spec asks for, 3:1 instead of 16:7 with the clear zone at 40% instead of 60%, and the mobile version is an opaque portrait rather than a transparent 8:7 crop. It fits the block beautifully, so I framed to the art, which costs a mobile aspect-ratio override and a tablet content cap. Both are scoped to .hero--release and commented for deletion, because the ticket says this image is temporary and the illustrator's real file lands later. One artefact survives at exactly 768px, where the title's closing bracket grazes the pigeon's wing; clearing it would cost a two-line title and a three-row button stack, so it stays for now. The images themselves are gitignored, so they still need pushing to each bucket by hand before this shows up anywhere but a local checkout.
The 1.92 illustration bleeds off the top edge of its own canvas, so any frame taller than the art left that crop showing as a hard horizontal line partway up the hero. The block is only 3:1 at 1440, which is why that was the one width that looked right. The culprit turned out to be the shared 104px top padding: it forced the block taller than the art at every narrower width, so rather than cropping the art to fit the block, the block now follows the art at 3:1 and the padding comes down with it. The content is centred, so it only needs room, not that much of it. From 900 up the art sits flush and the crop is off-frame entirely. Below 900 the sums stop working. The header overlays the hero and wants about 72px of clearance, and at 768 the art leaves a clear zone only 311px wide, so the title wraps to two lines above three rows of buttons. That is 208px of content, and a 3:1 block would be 256px, so forcing it hid the title behind the nav. The block stays a little taller there and the leftover 56px edge tucks in behind the header pills, where you cannot see it. Mobile had the same problem from the same cause, so the portrait scene now fills the block with the text over it instead of stacking below, which also brings that hero back from 796px to 600px. Also in here: the dark wash over the scene is gone, and since white type on a bright sky only manages 1.84:1 the title takes the on-accent ink instead, which holds in both themes because that token does not flip. The mobile fill needed dark-mode selectors of its own to beat .dark .hero--with-background-image. The title no longer collides with the pigeon between 1280 and 1345. And the content is lifted above the art frame, the way community already does it, because an absolutely positioned frame paints over the button row wherever the art behind it is opaque. Heads up on two things a designer should weigh. The hero is now shorter than Figma's 400 and 480 below 1440: 312 at 768, 300 at 900, 427 at 1280. And on phones the text sits over the illustration rather than above it. Both are the price of losing the hard line without cropping the picture, and both go away with on-spec art, which the ticket says is coming. The one literal colour, #5AB8EC, is sampled from the artwork's own top row so the mobile fill meets it exactly; it belongs to this temporary image rather than to the palette.

My own edit in the previous commit left an extra closing brace after the mobile block, so the stylesheet had one } too many. Browsers recover from that by ignoring it, which is why the hero still rendered correctly everywhere and why the test job went green, but it is invalid CSS and any parser stricter than a browser trips over it. CodeRabbit caught it. While in there, the --hero-fg-aspect override for this hero is gone too. The mobile frame now sets aspect-ratio: auto, so nothing ever read that variable any more, and its comment still described the frame following the art through it, which stopped being true when the scene started filling the block. No rendering change: heights, art placement, object-fit, background colour and all five hero links measure the same at 360, 390, 768, 900, 1280 and 1440 in both themes.
Requested look: dark mode gets white type over the scene rather than the near-black ink light mode uses. --color-primary-white is the primitive so it holds in both themes; --color-text-reversed would flip, and the wrong way. Heads up, this is a knowing contrast trade-off. The illustration keeps its bright sky in both themes, so nothing behind the title gets darker when the theme flips. Measured off the rendered page with the glyphs hidden, white sits at 1.7 to 2.0:1 against that sky at 390, 768, 900, 1280 and 1440, under the 3.0:1 minimum for large text. The near-black it replaces measured 10 to 11.5:1. The comment above the rule says so and says what would fix it properly, which is giving the scene a dark treatment so dark mode stops being a bright block in a dark page. Until that happens, swapping the colour back to a token is the wrong move.

Fix the dark-mode contrast failure before merge.
These selectors force white text over a bright scene. The documented 1.7–2.0:1 contrast is below the 3.0:1 minimum for large text. Dark-theme users may be unable to read the release title and description. Add a dark scene treatment or overlay before using white text, or retain an accessible dark text color until the artwork supports white text.

Light mode should match dark, so the title is white everywhere now. That is what the shared `.hero--with-bg-and-image` rule already does, so this deletes the release-specific colour overrides rather than adding another one. Twenty-four lines less CSS, and one fewer place for the two themes to drift apart. Heads up, unchanged from the last commit and now applying to light mode too: with the dark wash off, white type sits on the bright sky at about 1.8:1, under the 3.0:1 minimum for large text. That is a deliberate call for the look. The note moved onto the rule that actually causes it, the one switching the wash off, and it says the fix is to darken the scene rather than re-colour the type.

Summary & Context
Adds the 1.92 illustration to the release detail hero (the page with the downloads table), wiring the three image URLs through
core/hero.pyas the home and community heroes do.The template already passed
hero_image_url,hero_image_url_mobileandhero_background_image_urlto_hero_library.htmland nothing set them, so the hero rendered as a flat yellow surface.releases-page/even held the 1.91 art, referenced nowhere.The artwork is the temporary AI-modified file from the ticket. The real version swaps in at the same three paths with no code change.
Changes
core/hero.py: newrelease_hero_context().versions/views.py:get_v3_context_data()merges it in.templates/v3/release_detail.html:fullbleed_fg=True, so the scene uses the shared.hero-fgframe instead of the 488x416.hero__imagebox, as community does.static/css/v3/heros.css: the block now matches the art's 3:1 aspect instead of Figma's fixed 400/480; the dark wash is off; the title takes--color-text-on-accent; the content is lifted above the art frame; the mobile scene fills the block. All scoped to.hero--release, commented for removal with the temporary art.versions/tests/test_views.py: four tests covering the three context URLs, the full-bleed frame, and the mobile<source>being present when a crop is given and absent when it is not.static-large/img/v3/releases-page/:release-foreground.png(1536x512, transparent, 155KB),release-background.png(1536x512, 100KB),release-foreground-mobile.png(768x1182, 221KB). 516KB total.Why the block height changed
The art is exactly 3:1 and bleeds off all four edges of its canvas. Off the bottom and sides that is fine; off the top it is not, because a block taller in proportion letterboxes the art and leaves that cropped edge mid-hero as a hard horizontal line. The block is 3:1 only at 1440, which was the one width that looked right.
The shared 104px top padding was what forced the block taller than the art, so the block now follows the art and the padding comes down with it. From 900 up the art sits flush. Below 900 the sums fail (the header needs ~72px clearance, and 768 leaves a 311px clear zone, so 208px of content against a 256px block), so the block stays slightly taller and the residual 56px edge tucks behind the header pills. Mobile had the same cause, so the portrait scene fills the block with the text over it, which also took that hero from 796px to 600px.
The three PNGs are not in this PR (
static/static-large/*is gitignored), but they are already uploaded tostage.boost.org.v2,boost.org-cppal-dev-v2andboost.org.v2. Notejust up_sync_imageswas not used: it syncs the wholestatic-large/tree and would have overwritten 8 unrelated home and community images that differ between local and the buckets. The three files were copied individually instead.The hero is shorter than Figma below 1440: 312px at 768, 300 at 900, 367 at 1100, 427 at 1280, 480 above, against 400 and 480. On phones the text sits over the illustration rather than above it. Both are the cost of losing the hard line without cropping the picture, and both revert with on-spec art. Worth a designer's eye.
One hardcoded colour,
#5AB8EC. The mobile scene is opaque and carries its own sky, so the section behind it must meet that sky exactly or the join shows. Sampled from the artwork's top row and commented as belonging to this temporary image. The design-tokens box below is unticked for it.The dark-mode title fails contrast, deliberately. The illustration keeps its bright sky in both themes, so nothing behind the title darkens when the theme flips. White measures 1.7 to 2.0:1 against that sky at 390, 768, 900, 1280 and 1440, under the 3.0:1 minimum for large text; the near-black it replaces measured 10 to 11.5:1. White was chosen for the look. The proper fix is a dark treatment for the scene so dark mode is not a bright block in a dark page, at which point white earns its contrast. The rule carries a comment saying so. Light mode is unaffected at 11.3:1.
The artwork does not match
ILLUSTRATOR-HERO-SPEC.md, which asks for a 16:7 transparent cutout with the left 60% clear plus a transparent 8:7 mobile crop. This is 3:1 with content from 40.5% rightward and an opaque 13:20 portrait. I framed to the art, and the CSS above is the cost.Pre-existing:
_hero_library.htmlmarks the foregroundloading="lazy"while it is this page's LCP element, on this hero and the other two.Verification
