/* ─────────────────────────────────────────────────────────────────────────
 * design-systems/sentry/tokens.css
 *
 * Structured token bindings for "Design System Inspired by Sentry".
 * Dark-mode-first developer tool aesthetic: deep purple-black canvas
 * (#1f1633, #150f23) lit by warm purples (#6a5fc1, #79628c, #422082)
 * and punctuated by a signature lime-green pop (#c2ef4e).
 *
 * This file pre-compiles the values described in `DESIGN.md` into the
 * shared schema. Agents generating an artifact for Sentry should paste
 * the `:root` block verbatim into the first `<style>` of the artifact,
 * then reference everything via `var(--*)`.
 *
 * Brand-specific schema decisions (each one bends a schema convention
 * to match Sentry's "monitoring for developers" voice):
 *
 *   1. `--bg` is `#1f1633` — DESIGN.md §2 names this "the defining
 *      color of the brand". Never `#000000` — the warm purple-black
 *      is what separates Sentry from a generic terminal-dark UI
 *      ("Warm purple tones replace the typical cool grays of
 *      developer tools" — DESIGN.md §1). `--surface` recesses to
 *      `#150f23` (the documented "deeper sections, footer" tier).
 *      Cards visually lift via inset/ambient shadow and frosted
 *      glass overlays, not via a lighter solid surface — Sentry's
 *      depth language is light-on-dark, not paper-on-paper.
 *
 *   2. `--accent` is Sentry Purple `#6a5fc1` (the documented link /
 *      hover / focus color from DESIGN.md §2 + §9), not the famous
 *      lime green `#c2ef4e`. The schema's `--accent` slot is the
 *      cross-brand interactive anchor — links, focus rings, hover
 *      states — and DESIGN.md explicitly maps that role to Sentry
 *      Purple. Lime green is the brand's "pop" highlight ("once per
 *      section maximum" per DESIGN.md §9), which appears as a
 *      single deliberate hex in components.html where the design
 *      intent justifies it; it does not earn a shared schema slot.
 *
 *   3. `--focus-ring` is a sharp 2px solid ring at `var(--accent)`,
 *      not the schema's 3px alpha glow. DESIGN.md §4 documents the
 *      focus outline as `rgb(106, 95, 193) solid 0.125rem` — a
 *      crisp engineered indicator. The atmospheric glow form would
 *      blur into the warm purple bg and lose legibility against
 *      `#1f1633`.
 *
 *   4. `--font-display` leads with "Dammit Sans" — Sentry's
 *      irreverent display face used "ONLY for hero/display headings"
 *      (DESIGN.md §7). Rubik sits second in the stack as the
 *      workhorse fallback so any heading that loses Dammit Sans
 *      degrades to Rubik (the brand's primary UI face), not to a
 *      generic sans. `--font-body` is Rubik-first with the
 *      DESIGN.md §3 fallback chain. `--font-mono` is Monaco-first
 *      because Sentry's "developer-tool trinity" (DESIGN.md §1)
 *      explicitly chose Monaco over the schema's SF Mono default.
 *
 *   5. Type scale tops at 88px (`--text-4xl`) with `--text-3xl` at
 *      60px. DESIGN.md §3 documents Display Hero at 88px Dammit
 *      Sans weight 700 and Display Secondary at 60px — the brand's
 *      voice ("Code breaks. Fix it faster.") reads BIG by px count,
 *      not just by tracking compression. `--tracking-display` is
 *      `normal` because DESIGN.md §3 explicitly specifies
 *      "letter-spacing: normal" at hero scale; the typographic
 *      drama lives in size and weight, not in negative tracking.
 *
 *   6. `--leading-tight` is `1.2` (the upper end of DESIGN.md §3's
 *      documented "1.10–1.25" heading range). `--leading-body` is
 *      `1.5` per the body row of the same hierarchy table.
 *
 *   7. Radius scale spans 6 → 8 → 12 → 9999 to honor DESIGN.md §5's
 *      five-step ladder (6 inputs → 8 buttons/cards → 10–12
 *      containers → 13 primary muted → 18 pill containers).
 *      `--radius-sm` recesses to 6px (form input floor) instead of
 *      the schema's 8px default; per-component 13px and 18px values
 *      remain inline where DESIGN.md is explicit about a specific
 *      shape.
 *
 *   8. `--elev-raised` reproduces DESIGN.md §6 Level 2
 *      ("rgba(0, 0, 0, 0.1) 0px 10px 15px -3px" — the standard
 *      card elevation). The signature ambient purple glow
 *      (`rgba(22, 15, 36, 0.9) 0px 4px 4px 9px`) is hero-specific
 *      and inlined per-component; encoding it into the shared
 *      raised tier would over-shadow every card.
 *
 *   9. Section rhythm is 80/64/48 (desktop/tablet/phone),
 *      matching DESIGN.md §5's "dark breathing room" floor of
 *      64–80px+ vertical padding between sections. Container caps
 *      at 1152px — Sentry's documented XL breakpoint max-width.
 *
 * Source contracts:
 *   - Standard token names: design-systems/_schema/tokens.schema.ts
 *   - A2 fallback parity:   design-systems/_schema/defaults.css
 *   - Lint enforcement:     apps/daemon/src/lint-artifact.ts
