/* ============================================================================
   MPK — colour gallery: twenty complete looks plus the shared glow engine.

   CASCADE CONTRACT — read before editing. Each tier is strictly stronger
   than the one above it, so document order never decides anything:

     1. Glow engine             :root                                 (0,1,0)
     2. Shared palette defaults [data-qai-palette]:not(…obsidian)     (0,2,0)
     3. Shared component skin   [data-qai-palette]:not(…) .thing      (0,3,0)
     4. Tone groups             :root:root[data-qai-palette="x"], …   (0,3,0)
     5. Palette blocks          :root:root[data-qai-palette="x"]      (0,3,0)
     6. Palette component fixes :root:root:is(…) .thing               (0,4,0)

   The doubled :root is deliberate: it buys one class-level of specificity
   so a palette can never lose to the shared defaults. Do NOT add :root to
   tiers 2 and 3 — that lifted them to (0,3,0) and silently swallowed every
   per-palette override, which is how the light palettes ended up painting
   white text on white paper and eight palettes ended up sharing one
   background texture.

   Every palette declares the same contract:
     bg / bg-2 / surface-rgb   the three surfaces
     a / b / c -rgb            the accent triad, as raw channels
     title / body / muted      the ink, tinted to the palette
     pattern / grid            its own background texture
     speeds + glow + pulse     its own rhythm and burn
   ============================================================================ */


/* 1 — GLOW ENGINE ==========================================================
   Everything that burns on the page is derived from the accent triad and one
   intensity dial (--qai-glow), so a palette only has to turn the dial. The
   engine covers Obsidian too: its colours are untouched, it just lights up. */
