/*
 * TC Birthday Mailer — admin theme.
 *
 * Visual language follows shadcn/ui (the Laravel 12 React starter-kit look): a near-neutral
 * palette, hairline borders, generous whitespace, one solid primary and everything else
 * quiet. Token values are shadcn's own v4 defaults, converted from OKLCH to hex because this
 * project ships no build step:
 *
 *   oklch(0.145 0 0) -> #0A0A0A   foreground
 *   oklch(0.97  0 0) -> #F5F5F5   muted surface
 *   oklch(0.922 0 0) -> #E5E5E5   border
 *   oklch(0.985 0 0) -> #FAFAFA   sidebar
 *   0.625rem         -> 10px      radius
 *
 * Two deliberate departures:
 *
 * 1. --primary is the Landover green, not shadcn's near-black. It is the only saturated
 *    colour in the interface, which is what keeps the product recognisably theirs while
 *    everything around it stays neutral.
 * 2. --muted-fg is #5D5D5D, not shadcn's #737373. Theirs measures 4.74:1 on white — fine —
 *    but muted text also sits on the #FAFAFA sidebar and #F5F5F5 chips, where it drops
 *    below the 4.5:1 AA floor. #5D5D5D holds 6.58 / 6.31 / 6.04 across all three.
 *
 * Everything is applied through Bootstrap 5.3's own component variables where one exists,
 * so components keep their built-in hover, focus, active and disabled behaviour.
