/* ============================================================
   Syncc — public homepage ("/") · design-mocks "Syncc — Home"
   Full-bleed responsive marketing landing: navy-aurora hero +
   floating glass My Day preview, feature grid, devices strip,
   trust line, footer. (Phone collapses to the single-column
   "Syncc — Home (iPhone)" shape.)

   Standalone page (index.html does NOT extend base.html). Loaded
   on top of brand.css, so the accent comes from the app's System-A
   brand tokens — pre-login has no per-user palette, so the mockup's
   [data-palette] layer is dropped and color follows the school/brand
   default (currently teal). The `--h-*` locals below are defined ONCE
   from those tokens (color-mix only); no component rule hard-codes a
   hex. The only literal hex are the OAuth provider logos (n/a here)
   and the rgba(255,255,255,…) glass tints the mockup uses.

   TOKEN MAPPING (mockup → brand.css):
     mock --navy           → --brand-navy / --brand-page-deep
     mock --accent         → --brand-teal
     mock --accent-bright  → --brand-teal-bright
     mock --card           → --h-card   (navy-derived)
     mock --ink / -2 / -3  → --h-ink*   (white-tint hierarchy)
     mock --hairline       → --h-hairline
