/* =========================================================
   Redline Motors · site-2026.css
   Shared foundation for the 2026 redesign: tokens, base, buttons, forms,
   header, footer and utilities. Inner pages can link this file and reuse
   .site-header / .site-footer / .btn / .field without the home-page CSS.
   Contrast (WCAG AA, computed): ink on bg 16.5:1 · muted on bg 7.2:1 ·
   white on red 7.1:1 · red-ink link on bg 8.7:1 · night-dim on night 11.0:1 ·
   night-red link on night 8.0:1 · success on bg 4.9:1 · control borders 3.6:1+

   READABILITY + MICRO-SPACING TOKENS (standing rules for every page that links this file)
   Type scale, fluid (390px -> 1440px):
     --t-display 44 -> 76 · --t-h2 32 -> 56 · --t-h3 21 -> 26
     --t-lede    17 -> 18  (lead paragraph, 18px on desktop)
     --t-body    16 -> 16.6 (paragraphs, inputs, descriptions; never below 16)
     --t-small   15 -> 15.4 (nav, buttons, table cells, notes, "sample" lines; never below 15)
     --t-meta    14 -> 14.3 (mono caps labels, eyebrows, badges, table heads; never below 14)
   Nothing on the page renders below 14px. Line-height: body 1.6, small 1.5, headings 1.05-1.2.
   Letter-spacing: display -.035em, h2 -.03em, h3 -.02em, mono/caps labels +.08em.
   Measure: paragraphs cap at --measure (66ch); lede at 56ch.
   Spacing: 4px base, only these steps (--s-1..--s-10): 4 8 12 16 24 32 48 64 96 128.
     label -> input 8 · icon -> text 8 · badge padding 4 x 8 · button 48 high (44 min) x 24 side
     list rows 16-24 · table cells 12 · heading -> paragraph 12-16 · card padding 24 (32-48 desktop)
   Tap targets: every link/button is at least 44 x 44 (inline text links in paragraphs excepted).
   Figures (prices, finance, hours, counts) use tabular-nums so columns and baselines line up.

/* =========================================================
   .img-fade · soft CSS edge fade for photographic images
   ---------------------------------------------------------
   HOW TO USE
   Add the class to the element that WRAPS the photo (a <figure>, <a> or <div>), never to a
   text container:
     <figure class="img-fade"><picture>...<img ...></picture><figcaption>..</figcaption></figure>
   The mask is applied to the <picture> (or a bare <img>) inside it, so captions, flags and
   badges stay crisp. Because it is pure CSS and targets whatever <picture>/<img> sits inside
   the wrapper, REPLACING THE PHOTO (new src, new <picture>, new file) KEEPS THE EFFECT. Nothing
   is baked into the image files.
   VARIANTS (all edges by default)
     .img-fade--l  .img-fade--r  .img-fade--t  .img-fade--b     one edge only
     .img-fade--x (left+right)   .img-fade--y (top+bottom)
   TUNING (custom properties, set on the wrapper or in a media query)
     --fade-size   length of the fade on every side (default clamp(24px, 6vw, 88px))
     --fade-x / --fade-y   override the size for left-right / top-bottom
     --fade-t --fade-r --fade-b --fade-l   1 = fade this side, 0 = keep it crisp
   BLENDING
     The fade is an alpha mask, so the photo dissolves into whatever is behind the wrapper:
     the page, a surface or a dark band (.on-dark) alike. Keep the wrapper's own background
     transparent so no box shows through. Do not fade an edge that touches the viewport edge.
   FALLBACKS
     No mask support or forced-colors mode: the mask is dropped, the photo shows in full with
     the normal 8px media radius. Nothing else changes, text is never placed over the fade.
