   MUSIC OF ME — skin for the project's Module.html player
   ----------------------------------------------------------------------------
   Loaded ONLY by Levels/Projects/Music of Me/Module.html — a structural clone
   of the standard grade player (Math8's Module.html). This file is a SKIN:
   colors, fonts, and surface treatments only. It must never move, resize, or
   hide an element — students rely on the tools being exactly where they are in
   every other LMEC module. Layout lives in the page's inline #eLayout styles;
   this sheet loads after them, so equal-specificity overrides win here.

   Theme ("a music stand under stage light"):
     stage (page)   #211a14  warm espresso dark
     keybed panels  #2b221a  side rail / GameBar cards
     paper (card)   #f8f2e4  ivory manuscript problem card
     ink            #2a2119  engraving ink on paper
     staff hairline #d9cdb4 / #cbb277
     brass accent   #c9973f  (on dark: #e0b25c; ink-on-paper: #7c5a1d)

   Fonts: "Instrument Serif" (title + the italic tempo-marking directions),
   "Albert Sans" (UI/body), "Noto Music" (note glyphs in the answer field and
   the ♪ Notes drawer).

   The blue → brass mapping is applied consistently: everything #0d6efd in the
   standard player (borders, SUBMIT, rail active state, drawer symbols, level
   card, progress line) turns brass here, same place, same size.
