/**
 * TubeRaker — Profiles ("Account") sub-app page styles
 * ----------------------------------------------------------------------------
 * The five profiles/*.html templates (view, edit, settings, portfolio,
 * achievements) reference a large component vocabulary — profile-hero,
 * profile-avatar, stat-card, stats-grid, section-title, toggle, settings-list,
 * form-grid, info-banner, portfolio-grid, achievement-grid, level-progress,
 * card--danger, card--gradient-warning, etc. — that is NOT defined in the eight
 * shared stylesheets the pages load (reset/variables/base/layout/components/
 * forms/modals/animations). That is the direct cause of the "out of place",
 * unstyled rendering (raw checkboxes, un-gridded stat tiles, no card rhythm).
 *
 * This file implements that whole vocabulary using ONLY design tokens from
 * variables.css. It is loaded AFTER the eight shared stylesheets (and after
 * animations.css) but BEFORE header-embed.css, so a small number of deliberate
 * overrides of shared classes (.progress-bar--light, container padding) apply
 * only on profiles pages.
 *
 * Rules honoured throughout:
 *   - rem only (no px anywhere; the viewport meta tag is the only px exception)
 *   - colours only via var(--…); theme handled by the [data-theme] token switch
 *   - mobile-first; every layout reflows from 22.5rem and scales up at 40/48rem
 *   - interactive/touch targets >= 2.75rem
 *   - hover/transform micro-interactions are reduced-motion-guarded
 *   - correct in BOTH light and dark themes
 */

/* ===========================================================================
   0. Locally-scoped tokens
   The achievements hero paints text/knobs on a THEME-INDEPENDENT brand gradient
   (--color-brand-accent → --color-brand-secondary), which is only defined in
   :root and never re-mapped for light mode — so it renders the same amber→violet
   in both themes and always needs a fixed light foreground. --text-inverse is
   deliberately NOT used: it flips per theme (#0f172a dark / #ffffff light), which
   would paint near-black text on the gradient in dark mode. This mirrors the
   established convention in components.css (`.btn--primary { color: white }`) and
   the sibling pages/entries.css (`--color-on-brand: #ffffff`). A shared-token
   request to promote these into variables.css is filed in shared_requests; until
   it lands the literals are centralised here only (never a second colour literal).
   =========================================================================== */

  --profiles-fixed-white: #ffffff;

/* ===========================================================================
   1. Page container / vertical rhythm
   layout.css gives .app-main no padding of its own; on profiles pages the
   shared-dashboard shell hides the local sidebar, so the content region is a
   single full-width column. Centre it in a max-width column with consistent
   side padding and section rhythm. The #main-content id keeps these rules
   winning over any equal-specificity rule that ships later in header-embed.css.
