/* SNRL design system — the single source of truth for every page.
 *
 * WHY THIS FILE EXISTS
 * Every page carried its own <style> block, so they drifted: different greys, different radii,
 * different header markup, and an accessibility fix applied to one page and not the others. The
 * homepage was rebuilt to the prototype and immediately looked like a different product from the
 * page one click away.
 *
 * These tokens are EXTRACTED from the rebuilt homepage rather than re-derived, so this file is the
 * design that is already live and verified, not a second interpretation of it.
 *
 * CONTRAST IS A CONSTRAINT, NOT A PREFERENCE
 * Every colour pairing here was measured before adoption. Worst case is --ink-3 on --surface-2 at
 * 4.55:1, which clears WCAG AA for normal text. The palette this replaced did not: its secondary
 * grey was 3.38:1 on the page background, and one rule compounded it with opacity to ~2.9:1.
 * DO NOT reduce a token's contrast with opacity. If text needs to recede, use --ink-3, which was
 * chosen for that job and still passes.
