/* fline.sh — the landing page.
 *
 * This is the "Fline Landing v2" design, implemented. Three things travel with
 * it and every rule below is checked against them:
 *
 *   1. One accent, and it means one thing. Filament green is the platform
 *      working, and it is the only colour this page uses to say so. Amber
 *      marks a limitation rather than a capability and stays rationed: the
 *      pipeline, the secrets card and the not-measured caveat that used to
 *      carry it were deleted on 29 August 2026, and today it appears in
 *      exactly one place, the status list's Not-yet column header. Blue,
 *      the platform's own machinery, and grey, a step that spent no model
 *      call, went with those same diagrams; nothing on the page is tinted
 *      with either any more.
 *   2. Serif for the argument, sans for the interface, mono for anything read
 *      as an identifier. A hostname, a digest and a tool name are mono because
 *      they are things you would type; a sentence never is.
 *   3. No external request. The three families are served from the binary, so
 *      the page that argues work should happen where it costs least does not
 *      open two connections to a font CDN to say so.
 *
 * Dark is the base. :root paints it, a reader with JavaScript off gets it, and
 * it is what this page has always shown. Light is a single override block,
 * :root[data-theme='light'], further down this file rather than a
 * prefers-color-scheme query, because theme.js already resolves the reader's
 * preference before the first paint and stamps the attribute itself. A media
 * query alongside that would not add a mode, it would add a second copy of the
 * same forty lines for the two to drift out of step on the next edit. The
 * privacy and terms documents ride the same tokens, in both palettes.

/* The light palette.
 *
 * :root stays dark. That is the brand's ground, it is what a reader with
 * JavaScript off gets, and it is what this page has always painted. Light is an
 * override rather than the base, and there is exactly one of it because
 * theme.js resolves the system preference and stamps the attribute. The
 * alternative, a prefers-color-scheme block plus a data-theme block, is the
 * same forty lines written twice and drifting apart on the third edit.
 *
 * Two greens live here and only one lives in the dark palette. #00e08a is the
 * filament and it is legible on near-black; as 11px type on off-white it is
 * not. So --fil carries a darker green that type can be set in, and
 * --fil-bright keeps the filament for large filled shapes where it still reads.
 * Nothing else about the colour rule changes: green is the platform acting,
 * amber means a person is required and stays rationed, nothing else is tinted.
 *
 * The ink ramp gets the same check. --dim, --mute and --faint are all read at
 * sizes small enough that WCAG's large-text exception never applies, so each
 * is set to clear 4.5:1 at the smallest size it is actually used at in this
 * file, not at the size a mockup would pick.
 *
 * AGAINST EVERY GROUND IT IS SET ON, and that phrase is the correction of 29
 * August 2026 rather than a restatement. The check used to read "against both
 * --void and --panel", and --faint's darkest ground is neither of them: the
 * footer is --sunk, which is where the token is read at 12.5px by both spans
 * and all five links. #6c736f measured 4.30:1 there and failed AA for seven
 * elements, while this comment claimed 4.66:1 and was right only about the two
 * grounds anybody had looked at. Naming the grounds is therefore part of the
 * rule now: a ratio without the ground it was measured against is the kind of
 * claim that passes review and fails a reader.
 *
 * The light palette's text grounds are --void #fbfaf7, --deep #f7f6f2, --sunk
 * #f2f1ec, --panel #ffffff, --panel-2 #fbfaf7 (the same value as --void) and
 * --input #ffffff (the same value as --panel), so --sunk is the darkest and
 * decides every one of these numbers. --track #e8e7e1 is a seventh, and only
 * --dim is ever set on it (.inline).
 *
 * --dim's smallest use is 13px (.tbl td) and its original value is unchanged:
 * 7.27 on --void, 7.01 on --deep, 6.71 on --sunk, 7.59 on --panel, 6.12 on
 * --track. --mute's smallest use is 12.5px (.field label) and #646f6a clears
 * 5.00, 4.83, 4.62 and 5.22 on the four it is set on. --faint's smallest use
 * is 11.5px (.tbl th and .contact-list em) and it is now #686f6b: 4.94 on
 * --void, 4.77 on --deep, 4.56 on --sunk and 5.15 on --panel. #686f6b is the
 * lightest value on this hue line that clears 4.5 on --sunk; the next step up,
 * #69706c, is 4.49 and does not.
 *
 * --mute and --faint now sit within a twentieth of a step of each other on the
 * lighter grounds, which is closer than the dark palette's pair and closer
 * than they were before this change. That is the constraint working rather
 * than a mistake to fix later: AA at 11.5 to 12.5px over a ground as dark as
 * --sunk leaves almost no room below --mute, and a ramp a reader cannot
 * resolve is a smaller fault than type a reader cannot read. (The selector
 * citations moved with the sections that used to carry the smaller examples;
 * the ratios themselves are a function of the colour pair, not the type size,
 * so deleting a section never invalidates the numbers, only the example
 * selector.)
 *
 * --ghost sits outside that check. It marks decoration rather than
 * information, the dash before a not-yet-built status line, never a sentence
 * a reader has to read, and the dark palette's own --ghost is already only
 * around 2.5:1 for the same reason. Chasing AA on a token whose job is to sit
 * quietly under the eye would undo the one thing it is for, so its value here
 * is unchanged and it stays exempt on purpose.
