   - Row hover NEVER swaps in a grey/dark background (it disturbs reading text). Hover = background
     stays transparent, border-color + color go accent. Badges/pills keep their semantic colors:
     they carry their own color rules which beat td inheritance, so they never flip gold - do not
     "fix" them by unsetting their colors (that strips the pill AND inherits the hover gold).
   - Nested cell-text wrappers that carry their own color (e.g. a host .uc-title/.uc-text class)
     BEAT td inheritance. If a host nests colored wrappers, it must add its own deep hover rule
     (target the wrapper under tr:hover). VERIFY BY READING THE TEXT NODE'S computed color, never
     the td's - the td can be gold while every visible glyph stays grey.
   - The stack breakpoint is a constant, not a token: @media cannot read var(). 768px = fleet
     convention (pay consoles); hosts with a different grid override .uc-table--stack behavior.
   - transition is limited to border-color + color. `transition: all` on cells makes whole-row
     reflows on hover and interacts badly with the stacked-card layout. */

/* theme.css: the fleet shared theme layer, v30 (ds/7 carried forward + hub v3 value alignment
   + light skins for the dapp.css classes). ONE source for the light-mode override rules used by
   the Next.js dapp family (bridge / swap / buy / get / sell / send) + receive.u.cash, the ULINK
   wallet drawer skin and the 3-state theme toggle styling. Load AFTER dapp.css (and in the
   ustrap bundle the alphabetical pattern order already guarantees that).

  Hooks: the Tailwind dapp family drives `html.light` / `html.dark` classes (set pre-paint by
  each app's THEME_INIT from the `ucash-theme` cookie: light | dark | system). The hub family
  drives `[data-theme="light|dark"]`; base rules below answer BOTH hooks.
  v30 changes vs ds/7: light line/border values aligned to the hub v3 tokens (ds/29), .glass
  goes plateless (no blur), gold text hues match the hub light ramp, and the void backgrounds
  get their light opacity. Dark visuals are untouched: every changed rule is light-scoped.
  Version law: ds/N directories are immutable once published; ship fixes as the next major. */
