/* ============================================================
   Phone Box — the smart focus lockbox
   Checkpoint Claim-Ticket direction: your phone is "surrendered" the way a
   restricted item is surrendered at a security checkpoint -- processed into
   a stainless tray, tagged with a claim ticket, and released only through
   that ticket's own rules. The WORLD (stainless tray, thermal ticket paper,
   rubber ink-stamp, steel structural chrome, Bebas Neue/Archivo/Courier
   Prime/VT323 type) is unchanged by this pass -- only the color roles below
   changed. Vanilla CSS, no build step, file:// friendly.

   Palette unification (user decision, see DESIGN.md): this file's :root now
   ports app/src/theme/theme.ts's MODES.dark + ACCENTS.dark.mint token
   values verbatim -- the same values dashboard.css already uses for
   dashboard.html/login.html -- rather than the prior bespoke Checkpoint
   palette (charcoal bg, coral accent). One palette across marketing site +
   dashboard + app now, instead of two. Status colors (--locked/--closed/
   --unlocked below) still map to the real firmware theme
   (Box-code/lib/lock_config.py) exactly as before -- locked/SEIZED,
   closed/HOLDING, unlocked/CLEARED -- just re-expressed as the app's own
   danger/warn/success roles, whose hex values already read as the same
   coral/amber/mint family (danger #ef4444 vs the old coral #ef5350; warn
   #f2b84b is an exact match; success #22c55e vs the old mint #35d07f) so the
   device mockup's on-screen status colors barely shift. The one deliberate
   semantic change: the page's PRIMARY brand accent (buttons, CTA emphasis,
   focus rings, selection) moves from the old status-red to the app's own
   accent role (mint, #22c55e) -- see --accent below and every rule this
   pass repointed from --locked to --accent (btn--primary, skip-link,
   ::selection, price-card--hero/waitlist__inner emphasis borders,
   setting__fill's slider gradient, cost-bars__fill--us). Steel/paper
   (structural chrome, thermal ticket material) are untouched -- neither is
   a "theme color" in the app's model, both stay their own achromatic/warm
   material colors regardless of accent. */

     the same gap. 18/22/26px are kept as half-steps (--space-4-5/-5-5/-6-5)
     rather than snapped to a neighbour: they carry ~45 call sites between
     them, so collapsing them is a visual change to make deliberately, not
     a side effect of tokenizing. Named after their px value (halves get a
     `-5` suffix, e.g. --space-2-5 = 10px) rather than t-shirt sizes, since
     the range needed here (2px hairlines up to 72px section rhythm) is
     wider than a t-shirt scale reads cleanly. Every step is still reachable
     by name; nothing in this file uses a bare px value going forward except
     truly one-of-a-kind component geometry (e.g. a 66px input width) that
