     same reasoning as --chrome-accent: the chrome bar they render
     against is always dark. -dot is the vivid picker-swatch color (shown
     on the light pin-panel surface); -bg/-border are the tinted versions
     used on the pinned pill/company-switch badge/sidebar stripe.
     -bg/-border were originally desaturated to blend into the dark
     chrome, but that made them hard to tell apart at a glance (user
     feedback 2026-09-05/09) — teal especially, since its hue sits close
     to --chrome-active's own. Re-tuned to real Tailwind 800/600 shades
     (same families as -dot's own 400/500 shades) for meaningfully higher
     saturation while staying dark enough to read as a tinted chip, not a
     bright pastel. No true red — that stays reserved for void/overdue/
     critical (see --critical above), so a user's color choice here can
     never read as a warning. */

/* ============ Buttons ============
   A four-tier UX-importance ladder, assigned per page based on what that
   page's own actions actually are (see CLAUDE.md's action-bar
   hierarchy) — not every page uses all four tiers, and a page can
   legitimately show more than one Primary1 action at once (e.g.
   bill.php's Edit and Post Bill are both Primary1 — each is, on its
   own, "the reason someone is on this page" for a different bill
   status).
     Primary1   .btn-primary          solid accent fill — top tier.
     Primary2   .btn-primary-outline  accent outline, transparent fill —
                                       same accent family as Primary1,
                                       one rung down.
     Secondary1 .btn-secondary        neutral border, solid surface fill
                                       — the plain default look below.
     Secondary2 .btn-secondary-outline neutral outline, transparent fill
                                       — one rung down from Secondary1.
   .btn-danger is a separate axis (destructive, not a rank) — see the
   ledger-red rule above.
   Every tier's hover fills in toward its own color rather than a single
   shared hover treatment, so the feedback language reads as one system:
   a solid tier darkens itself, an outline tier fills in with a soft
   tint of the same hue it's already bordered in.
