/* css/app.css: the Ondamare interface (Highframe concept no. 1), 1 Nov 2026.
   Layout and phone flow adapted from the Blu Marine app (10_BLU_MARINE/review/realism/integ/site/css/app.css, read only):
   the project card top left, the credits (i) and the compass top right with Reset view under them, the toolbar at the
   bottom, sheets above it on a phone and floating panels on a desktop. Highframe identity (PLATFORM_PLAN/brand/
   highframe_identity.html, dark tokens): ink #eef1f4, muted #98a2ac, line #29303a, brass #c8a473 on #0d1013; Sora for
   the project name, Instrument Sans for the interface; the steel blue of the Highframe mark (#bccbda) for the site pin.
   Every touch target is at least 44 px; panels never cover most of the 3D on a phone (WEB3D 4.2, 7.5). */
