/* ---- Button pair — wrap row + content-driven equal width ---
   A two-(or-more)-button CTA row that never clips or overflows: flex-wrap
   means it stacks instead of clipping when space runs out. Pair with the
   `buttonPairStyle()` helper (src/utils/buttonPair.ts), which sets
   --btn-pair-min-w from the longest label's own character count (a `ch`
   value — scales with the font) — NOT a guessed pixel breakpoint. min-width
   only ever WIDENS a button toward the longest one; it can never shrink a
   button below its own text, so there's no clipping risk either way.

   Applies the equal-ish-width treatment at every size by default. To scope
   it to one breakpoint only (e.g. mobile-only, like AirCtaSection), add a
   local override in the consuming component's CSS:
     .my-actions .btn { min-width: 0; }                          // reset
     @media (max-width: 767px) {
       .my-actions .btn { min-width: var(--btn-pair-min-w, 0); } // re-enable

   AirPricingPlanCard — shared plan card (tray + inner card + included

   AIR-specific — do not confuse with the VR/human-first PricingCard
   in pages/pricing/PricingCard.

   The card owns its own chrome/spacing/type. The consuming section
   owns the grid/flex wrapper around it (columns, gaps, breakpoints)
   — see docs/component-unification-playbook.md. `flex: 1; min-width: 0`
   below is just a safe default so the card expands wherever it's
   dropped; a section's own tablet/mobile CSS overrides it to stack.

   Desktop (min-width: 992px) alignment uses CSS subgrid (progressive
   enhancement via @supports) so the tier badge / subtitle / price /
   controls / included list line up across sibling cards regardless of
   content length. Any wrapper that opts in must set `display: grid;
   grid-template-rows: repeat(7, auto)` with a column count matching
   its own card count.

/* Subgrid path: align the card header/pricing/controls across sibling
   cards. The included feature lists stay in normal flow so shorter
   cards do not inherit awkward per-feature row tracks from the longest
   list. Self-contained (no dependency on a specific wrapper class) so
   it works under any consuming section's grid.

   Explicitly gated to desktop (min-width: 992px) — NOT just
   `@supports (grid-template-rows: subgrid)` on its own. `@supports` is
   a feature query, not a viewport query: on a subgrid-capable browser
   it stays "true" at every width, so its `display: contents` rules
   (higher specificity than the tablet media query's plain-class resets
   below) kept winning below 992px too, silently killing the tier→copy
   and subtitle→pricing gaps at tablet/mobile. Scoping by width removes
   that specificity fight entirely instead of trying to out-specificity it. */
