/**
 * SnS aside nav — styles (Session 44 page split).
 *
 * Tokens reference the dashboard's :root variables (oklch palette, --card,
 * --border, --muted-foreground, etc.). The aside lives outside the page-specific
 * card layouts so it doesn't inherit any section padding.
 *
 * Desktop (>=880px): fixed 220px column on the left, dashboard content gets
 * the right side. Mobile (<880px): aside collapses to a top accordion that
 * the hamburger toggle expands.
 */

/* Pages that use the new 220px aside override the dashboard's default 64px
   grid track. index.html (everything-page) keeps its 64px legacy track until
   it's rebuilt as pnl.html in step 7 of the page split. The `display: grid`
   declaration is repeated here for the calculator case — its baseline `.app`
   rule uses `display: block` (centred container), which would otherwise
   ignore grid-template-columns. */
/* TAT-055 (28 Apr 2026) — added "procurement" to the override list so the
   Log a buy page no longer sits behind the 220px aside. Also removed the
   calculator-centering `.main { max-width: 920px; margin: 0 auto }` rule —
   calculator now matches pnl/supply/sales full-width alignment per Kenneth. */
