/* =========================================================
   Open Road Driving · site-2026b.css
   Shared foundation of the 2026 redesign: tokens, base, type, buttons, forms kit, image utilities, header, menu, footer.
   Every page links this file first, then home-2026b.css (index) or inner-2026b.css (all other pages).

   BRAND: "quiet road signage". Warm cream paper, deep navy ink, ONE action colour: road-sign green (--brand, white text on it).
   Sunny yellow (--sun) is a fill and a highlight only, never text on light paper; it is the number-plate yellow of the price plates and
   the centre line that runs through the dark bands. Navy carries the dark bands. A small red is kept for errors only.
   Display: Bricolage Grotesque (variable, optical size). Text: Atkinson Hyperlegible Next (designed for legibility). Both self-hosted.
   Brand-specific variable names (--brand, --sun, --navy); never a generic accent name.

   NO MOTION: no transitions, animations, keyframes, smooth scrolling or hover lifts anywhere. Hover is an instant colour change;
   the focus ring stays. (document.getAnimations().length is 0 at rest.) The owner's one permitted exception (a 200ms border fade on link cards, only under
   prefers-reduced-motion: no-preference) is not needed here: this theme has no link cards, so nothing transitions at all.

   READABILITY (standing rules): nothing under 14px; body 17 -> 18; small 16 -> 17; meta 15; tap targets >= 44px;
   spacing on a 4px scale (--s-1..--s-10); figures use tabular-nums; paragraphs cap at 66ch.

/* =========================================================
   PREMIUM IMAGERY  ·  .img-fade (dissolving edges)  +  .img-frame (crisp, rounded, ringed)
   ---------------------------------------------------------
   Both are reusable CSS utilities. They style whatever <picture>/<img> sits inside the wrapper, so
   REPLACING THE PHOTO (new src, new <picture>, new file) KEEPS EVERYTHING. Nothing is baked into
   the image files. Captions, flags and badges live outside <picture>, so they stay crisp.

   MARKUP
     <figure class="img-fade"><picture>...<img ...></picture><figcaption>..</figcaption></figure>
     <figure class="img-frame"><picture>...<img ...></picture></figure>
   Use .img-fade for atmospheric / full-width photographs that should melt into the page (hero,
   flow, workshop). Use .img-frame for photographs inside cards and lists, where a crisp rounded
   edge reads as more premium than a soft one.

   WHAT EVERY PHOTO GETS (all tokens live in :root)
     tonal grade   filter: var(--img-grade)     very light contrast/saturation lift, never heavy
     vignette      picture::after, --vig        radial edge darkening, 0.16 by default, 0 = off
     placeholder   background: var(--img-ph)    shows while a lazy photo loads
     stability     keep width/height + aspect-ratio on the wrapper; object-fit: cover; no layout shift
   .img-fade extras
     --fade-size / --fade-x / --fade-y   fade length (default clamp(24px, 6vw, 88px))
     .img-fade--l .--r .--t .--b .--x .--y   which edges fade (or --fade-t/-r/-b/-l: 1 or 0)
     smootherstep ramp (9 stops per edge), so the dissolve has no visible start line
     hairline ring appears ONLY on edges that stay crisp (a 1px ring on a fading edge would be wrong)
   .img-frame extras
     radius var(--img-radius) 12px, inset hairline ring var(--img-ring), soft depth var(--img-shadow)
   --ring: transparent  on a wrapper turns the ring off (hero touches the viewport edges)

   FALLBACKS
     No mask support or forced-colors: the mask is dropped and the photo shows in full with the
     normal media radius. Photos are always static: no fade-in, zoom or Ken Burns.
