/* Where's Rocko? — Coloring Book (tap-to-fill).
   Loaded by /color/ on TOP of the shared /styles.css design tokens — same
   layering pattern as /spot/spot.css and /reveal/reveal.css. Warm "Creative
   Library" system (paper / surface / ink / brand #F04E37).
   Category is CREATE, so accents use the create hue. This is Create & Chill:
   no timer, no score, no win/lose — just color.
   The coloring "paper" (the canvas + gallery thumbs) is ALWAYS light in both
   themes, like a real coloring book page; the chrome around it adapts. */

/* =========================================================================
   PLAY VIEW FITS THE SCREEN — no page scroll, no inner scroll of #view-color.
   nav.js adds body.rk-playing while a play view is open and locks the page
   (html/body overflow hidden); landing.css then makes #view-color an internal
   scroller. Here we turn #view-color into a flex COLUMN that fills the locked
   height: HUD / brush bar / palette / caption / tools stay one compact row
   each (horizontal-scroll strips), and #stage flexes to fill the leftover
   space and CLIPS — it is the zoom viewport (zoom.js). The picture is fit
   inside via contain, so nothing overflows. The gallery (#view-gallery) is a
   page list and is left completely untouched (it still scrolls normally).
   Any #stage-scoped selector out-specifies landing.css's section rule.
