/* ═══════════════════════════════════════════════════════════════════════════
   Letterboxd Toolkit — shared chrome
   Tokens, reset, nav, buttons, footer, grain, scroll furniture. Everything a
   second page needs; page-specific layout stays inline in the page itself.

   Standing constraint: this site makes ZERO external requests. No webfonts, no
   CDN, no analytics, no hotlinked images. A product whose whole pitch is "we
   send almost nothing" cannot have a marketing site that phones home to three
   other companies before the headline paints.
