/* ============================================================================
   Forge Marketplace — design tokens and base styles
   ============================================================================

   NO BUILD STEP, DELIBERATELY. `MARKETPLACE_UI_DIST` points at this directory
   in source (blueforge.config.json), and the API serves it statically. Adopting
   Tailwind would mean a build, a dist directory, and changes to the deploy
   config, CI, and that serving assumption — for a UI that is eight static HTML
   pages and one script. Custom properties give the same tokens natively.

   Every colour below is a token. Nothing downstream hardcodes a hex value, so
   the dark theme is a token swap rather than a second stylesheet.

/* ── Forms and controls ───────────────────────────────────────────────────── */

/* ── Tap targets ────────────────────────────────────────────────────────────
   Apple's HIG asks for 44px, and WCAG 2.5.5 (AAA) agrees. WCAG 2.5.8 (AA) is
   the looser 24px, and carries an explicit exemption for targets inline in a
   block of text.

   That exemption is why this is not a blanket rule. Links inside page content —
   a package name in a table cell, `pub_acme` in a row, a link mid-sentence —
   are inline targets sitting in a line box; padding them to 44px would push
   their own text apart and change how the table reads. They are left alone
   deliberately.

   What is covered is the standalone controls: form fields and buttons, which
   measured 38px (and one signup field at 21px), and the header nav, whose links
   measured 18px. Those are discrete controls, not prose.       (from PR #34) */
