/* ============================================================
   RAYDO DESIGN SYSTEM — RDS v2.6 · Tokens
   THE single source of truth. Import it; never restyle ad hoc, and
   never redefine a token inline on a page. A rebrand is this file.

   v2.0 (27 Jul 2026) — "The Ring & the Sun" · Tim's upgrade rulings
     NEW MARK   the R monogram (brand/raydo-r-monogram-*.svg) is the
                logo. The current flows through the letter. The old
                Lift-off composition retires from logo duty; its DNA
                (rail · ring) lives on as component grammar.
     GRAMMAR    simplified to three: the RING (the iconic moment, the
                one state container), the RAIL (quiet structure — a
                component, not an icon), and ATTENTION (marigold).
                The rider is RETIRED as core grammar; --rds-rider* and
                --rds-bead are kept only as deprecated aliases so old
                surfaces don't break. Do not use them in new work.
     ATTENTION  the one law that identifies us: marigold #f2b134 is
                the attention colour. Wherever Raydo wants your eye,
                marigold marks it — and only ONE marigold point per
                view. An open ring alone is a state, not an ask.
                (--rds-attention, §G)
     RING       substate geometry tokens (§G) — rest · attention ·
                hover (the gap narrows) · pressed · working (the arc
                rides) · done (closes, draws its tick) · expired.
                The ring speaks with geometry, never with icon salad.
     GRADIENTS  §2b — the clean gradient grounds (CSS, grained). For
                highlight surfaces where the live Current is not
                earned or not possible (decks, cards, og-images,
                email). Always rising to the upper right.
     CURRENT    silk now has two named variants (see js/current.js):
                Sovereign Pure (no marigold at all) and Sovereign
                Sunrise (opts.sun — the sun felt behind the silk).
                The lines/strand-field mode is RETIRED.
     ICONS      §5b — the utility icon set (94 icons, icons/, 24-grid,
                stroke 1.75). Utility icons never sit inside the state
                ring; the ring-verb vocabulary is retired (the tick is
                the only glyph a ring ever draws).
     SPACE      section-rhythm tokens (§4) + the box-in-box rule:
                one bordered container per nesting path.

   v1.9.1 (25 Jul 2026) — alignment pass (index.html is canon)
     REMOVED   31 tokens with zero references anywhere in rds-v1 (not
               index.html, not base.css/components.css, not the other
               HTML surfaces, not the JS layer): the pre-ember-discipline
               oat/rose ramp remnants (COLOUR-RECOMMENDATION.md already
               called for oat's demotion — the ramp just hadn't been
               trimmed), the icon-sm/md/lg/icon-stroke scale superseded
               by the v1.9 stroke-ring/glyph/hair unification below, and
               a handful of orphaned scale-steps (border/border-strong,
               radius-full, elev-0, weight-bold, tracking-normal, space-1,
               ease-breathe/exit, z-base/raised/modal, bare --rds-surface/
               -value/-value-soft/-alert-soft superseded by their -raised/
               -paper/-ink/-soft(rescued) siblings).
     FLAGGED   (kept, not deleted — these name real brand signatures or
               product rules with no consuming component yet; that's a
               build decision, not cleanup): the Living Line's dedicated
               token block (§ below), the grammar's ring-gap angle, the
               cadence/presence/message-limit constants. See
               DESIGN-VISION.md system review + COVERAGE.md for what
               each maps to.
     RESOLVED  (25 Jul 2026, same day) — .rds-voice-wave now reads
               --rds-line-stroke/-width/-rider instead of re-declaring
               the same values by hand (RDS-101); the two hand-typed
               rotate(-64deg) rules now read --rds-ring-gap-deg via
               calc() (RDS-102); --rds-liftoff-angle REMOVED per call —
               unused anywhere, confirmed not needed (RDS-103).

   v1.9 (4 Jul 2026) — the token file finally tells the truth:
     MOVED IN  the v1.6 signal decision (ember = the marigold signal
               #f2b134) that used to live as a per-page <style id=
               "signal-layer"> override — the source of ~84 hardcoded
               hex and of channels.html rendering off-canon.
     ADDED     --rds-ember-mist / -paper / -rgb (attached glows)
     ADDED     --rds-stroke-ring 1.6 / --rds-stroke-glyph 1.4 (§5) —
               one lean stroke scale; the canonical done-tick geometry
     ADDED     --rds-motion alias (§8) — was referenced, never defined
     CONVERGED --rds-wait / --rds-value / --rds-value-ink to the v1.6
               CORE so every surface (index · channels · platform)
               reads the same signal.

   Lineage (v1.0 "Groundwork", full reasoning in DIRECTION.md):
     KILLED  --rds-current-mesh (CSS blob gradients) → js/current.js shader
     KILLED  glass tokens (--rds-glass-*)            → white + hairline + ink
     KILLED  tilt (--rds-tilt-*)                     → press depth (physics)
     KILLED  page blooms/washes                      → 2% paper grain only
     NEW     rail / ring / bead grammar constants (§G)
     NEW     press-depth elevation model (§7)
     KEPT    all colour scales, inks, type, space, radius, motion
             laws, presence, message anatomy.

  /* ---------- G2 · THE RING MOMENT ----------
     One state container. Seven substates, told by SHAPE first — every
     state is distinguishable in pure greyscale, so colour only ever
     amplifies what the geometry already says.

     THE MOUTH TURNS. An ordinary open ring rests with its mouth at the
     UPPER RIGHT (315° clockwise from 3 o'clock, 1:30) — the direction
     the Mark releases in, and the direction everything else in the
     system rises toward. An ASK turns its mouth to the UPPER LEFT
     (225°, 10:30), where the eye enters a surface. So a request is
     distinguished from a state twice over — by orientation and by the
     light it holds — and both survive greyscale.

     Within a state the mouth is ANCHORED: rotation moves with the dash
     so the ring closes IN PLACE, never spinning to a new position.

     Canonical 24-view: c=12, r=9, C=2πr=56.55.
       rest      open at the upper right, modest mouth (56°), ink —
                 a state, not an ask
       attention the mouth TURNS to the upper left, opens wider (77°),
                 and the ring HOLDS A WARM LIGHT — a soft marigold disc
                 inside it. Work is sitting in the ring, waiting for
                 your decision. The light is a value, not just a hue,
                 so the ask reads with the colour taken away.
       hover     the mouth closes in on the light (24°) and the light
                 rises to meet the stroke — still visibly open
       pressed   the mouth SHUTS and the whole ring compresses (0.93)
                 and sits 1px down: committed, never a bounce
       working   a sage arc rides a faint closed track (the only loop);
                 the light dims — it is no longer yours to act on
       done      the ring closes, the light is spent, and the tick
                 draws in its place
