/* Immutable QC · ui/theme.css: the shared design system of the landing page (index.html) and the app (app/).
   "Luminous lab" (design decision 2026-10-13): a dark, calm instrument surface; one cyan signal for a pass and a seal,
   coral for a fail, amber for notes. Every state also has an icon and a word. No external request: the fonts are the
   site's own (../fonts/), nothing else is loaded. Icons: ui/icons.svg. Tests: ui/test/ (node --test ui/test).

   RULES
   - Restraint: a glow (--glow-*) only on the seal, the main action (.btn-primary) and a pass (.verdict-pass). No
     gradient text but the hero headline (.text-grad). It must read as a lab instrument, never as a launch page.
   - State colors: --signal (cyan) = pass, match, sealed; --alert (coral) = fail, changed, missing; --note (amber) =
     notes only, never a failure. Never color alone: pair it with an icon (ui/icons.svg) and a word.
   - Contrast (WCAG AA, checked by ui/test/theme.test.mjs): body text --ink/--ink-2/--ink-3 and the state colors are
     at least 4.5:1 on every surface token and on their own soft tints; --line-ui (input borders, control outlines)
     is at least 3:1 on every surface.
   - Fonts: Archivo (the site's static instance, width 115, weight 620 only: --display at 620), IBM Plex Sans 400,
     IBM Plex Mono 400 and 500. font-synthesis is off, so ask for no other weight (strong/b synthesize their weight).

   COMPONENTS (class: usage)
   Layout     .wrap: centered column with the side gutter · .section: a page band (border on top, --section-y
              padding) · .section-h: a section's eyebrow + h2 + intro · .stack: vertical rhythm (--flow, 1em)
              · .sky: the hero background (soft glow and a faint grid) · .grid-2/.grid-3: equal columns, one on
              phones

              (never wraps) · .vh: visually hidden, still read (use .vh for "Upcoming:" prefixes and icon-only labels)
              · .skip: the "Skip to content" link
   Header     .strip > .wrap > .status-line: the status band on top · .site-header > .wrap > a.brand + nav.site-nav
              (ul > li > a, aria-current="page"; li.nav-opt hides below 720 px; Docs stays) · .brand: <svg class="mark">
              (i-mark) + <span class="brand-name">Immutable QC</span> (the name is visually hidden below 360 px)
   Footer     .site-footer > .wrap > nav.foot-nav (ul) + .foot-meta (.status-line, contact) + p.indep
   Status     .status-line: <p class="status-line"><span>Independent project ·</span> <span>Open alpha ·</span>
              <span>No customers yet</span></p> (each segment never breaks inside; the dot stays with its segment)
   Buttons    .btn + .btn-primary (cyan, glow: the one main action) | .btn-ghost (outline) | .btn-quiet (text only);
              .btn-s (small) · .btn-block (full width) · disabled or aria-disabled="true" · svg inside sits at 18 px
              · .icon-btn: square icon button (give it a .vh label) · .copy: small "Copy" button; data-copied on it
              shows the done state · .btn-row: a wrapping row of buttons
   Toggles    .seg: segmented control (a or button children with aria-current or aria-pressed="true")
              · .filters > .filter: filter chips with a count, <button class="filter" aria-pressed="true">All
              <span class="n">5</span></button>
   Tags       .tag + a state: .tag-match .tag-pass .tag-sealed (cyan) | .tag-changed .tag-fail .tag-missing (coral;
              missing is dashed) | .tag-note .tag-unsealed (not sealed, dashed) .tag-back (back after removal) (amber)
              | .tag-removed .tag-unchecked (neutral) | .tag-upcoming (neutral, dashed); .tag-l larger. Markup:
              <span class="tag tag-changed"><svg aria-hidden="true"><use href="ui/icons.svg#i-x"/></svg>Changed</span>
              · .chips > .chip: sentence-case items (the Upcoming list); .chip-upcoming is dashed
              · .live-dot: a small cyan dot that may glow (seal, watching)
   Surfaces   .glass: the premium panel (edge light, shadow) · .panel: a flat inner panel · .card: a section card;
              .card-n: its numbered label ("1 · Download") · .callout + .callout-pass | .callout-fail | .callout-note
              | .callout-info: an icon and a sentence in a tinted box · .verdict + .verdict-pass | .verdict-fail:
              .verdict-ic (svg), .verdict-text (tag, h2 or h3, .verdict-meta), .verdict-actions
              · .stats > .stat (.stat-ok | .stat-bad | .stat-note | .stat-zero): <b class="stat-n">, <span
              class="stat-l">
   Data       .hash: a SHA-256 in 8-character groups, <code class="hash"><span>57620ea6</span><span>…</span></code>
              (no whitespace between the spans: lines break only between groups, a copy gives the bare hex);
              .hash-sealed (cyan) .hash-changed (coral); <mark> inside a group marks a changed character;
              .hash-l larger; .hash-short: one group and an ellipsis on one line (<span>1702711c</span>…) · .kv: a definition list of key and value rows (dd.kv-copy: value + .icon-btn)
              · .table: a data table (th, td, .num right-aligned and tabular; tr.is-problem, tr.is-note); add
              .table-stack to turn rows into cards below 720 px (each td needs data-label="Size" etc.);
              .table-scroll: a wrapper that scrolls a wide table sideways instead
              · .cmd: the command box, .cmd-h (label + .copy) and <pre tabindex="0"> that never wraps and scrolls
              sideways inside its box; .pr is the prompt (aria-hidden) · .meter > span: a progress bar (set
              --p from 0 to 1 on .meter with element.style.setProperty) · .list-check: a list with check marks
   Forms      .field (label + .input + .hint) · .input (also input[type=text|search]) · .search: an input with an
              icon at the start · details.fold > summary: a folded section (chevron drawn in CSS)
   Icons      .ic: an inline icon at 1.25em (svg); every svg in .btn, .tag, .callout, .stat is sized for you. Symbols
              in ui/icons.svg (<use href="ui/icons.svg#i-check"/>; the page's CSP needs img-src 'self' for that)
   Media      prefers-reduced-motion: no transition or animation · forced-colors: borders and focus stay visible,
              state icons and words carry the meaning · print: a light, ink-only version (controls hidden, links and
              hashes printed in full)
