/* style.css — conservative cleanup of style.css
   ============================================================
   Changes from style.css:
   • Added missing --te-orange: #f0690a to :root (single var, *all* references use it)
   • Removed duplicate @keyframes ready-pulse / tutorial-pulse-text
     (identical to pulse; classes now reuse pulse)
   • Consolidated duplicate .scope-wrap & .meter-track declarations
     (kept final winning values)
   • Combined .ceremony-overlay + .settings-overlay duplicate rules
     (verified byte-identical declarations)
   • Combined .ceremony-card + .settings-card shared declarations
   • Preserves original cascade behavior and source-order semantics
   ============================================================ */

/*
Keep @supports local when the fallback is implementation-specific.

Reserve root tokens for semantic design values (palette, spacing,
radii, typography), not browser capability indirection.
*/
/* 
    Here's what changed and why:
    New tokens added to :root:

    - [x] --surface-deep — meter track background (was #3a342c)
    - [x] --scope-bg — oscilloscope background (was #211d18)
    - [x] --red-dark / --red-deep — stamp-fail fill and border (were #8b1a1a, #5a0a0a)

    Replaced with color-mix(in oklch, ...):

    - [x] .crt-btn:hover and .level-select-btn.unlocked:hover — derived from --surface2
    - [x] .crt-btn.danger:hover — derived from --coral
    - [x] .type-btn.active box-shadow — derived from --coral
    - [ ] Stamp borders for hint, skip, success — derived from --amber, --coral, --cream
    - [x] #game box-shadow bottom — derived from --bg
    - [ ] Slider thumb resting/active states — derived from --cream

    The token block is now the single source of truth. If you change --coral, the hover state and stamp border follow automatically.
