 * kc-door.css — /account, on the token layer
 * =============================================================================
 *
 * WHAT THIS FILE IS
 *
 * The only stylesheet /account loads on top of the token layer. It used to
 * serve /signin too; that door now wears the shared landing skin
 * (kc-landing-skin.css + kc-signin.css, 2026-09-13, "make the rest of the
 * entire platform look the same"), so the sign-in-only rules — the two-column
 * shell, the invitation, the tab strip, the providers, the truth panel — left
 * this file rather than being overridden there. What remains is what
 * account.html's markup wears.
 *
 * LOAD ORDER, and it matters
 *
 *   kc-theme.css   the register system: --fs-*, --r-*, --bw-*, the font slots
 *   kc-uplift.css  data-theme x data-surface, and LAYER 6 which paints the page
 *   kc-door.css    this file — components only, values only from the two above
 *
 * Tokens for every colour, radius, weight and size; layout numbers (max-widths,
 * gaps, one-off measures) are the only literals. There is not a single hex
 * value below, and no font name: the faces come from kc-theme.css, which now
 * names Comfortaa (display) and Nunito (everything else).
 *
 * THE FOUR MODES AND THE THREE REGISTERS
 *
 * Nothing here selects on data-theme or data-surface. It cannot need to: the
 * token layer resolves --plate, --inset, --ink1..3, --blur and --shadow per
 * mode, so a component written once holds in all four. `clear` is selected on
 * only for motion: --door-ease below is the single switch, and it is also 0s
 * under prefers-reduced-motion.
 *
 * EVERY INK/GROUND PAIRING BELOW IS ONE tools/contrast_audit.mjs MEASURES
 *
 *   --ink1/--ink2/--ink3  on --plate, --inset, --recess, --quiet, --acc-quiet,
 *                            --green-tint, --amber-wash, --crit-tint,
 *                            --page, --chrome
 *   --acc                 on --plate, --inset, --tint-acc, --acc-quiet, --quiet
 *   --green               on --plate, --green-tint
 *   --amber               on --plate, --amber-tint, --amber-wash
 *   --crit                on --plate, --crit-tint
 *   --on-grad             on --grad
 *   --on-acc              on --acc-deep
 *   --check-ink           on --check-bg
 *
 * Where a component would have put a semantic ink on an UNMEASURED ground the
 * ground was removed rather than the ink: `.rules` and `.methods li` carry a
 * rule and no fill precisely so that --crit and --green land on --plate.
