/* =========================================================
   Volt Lane · site-2026.css
   Shared foundation for the 2026 redesign: tokens, base, buttons, forms,
   utility bar, header, mobile menu, footer and the .img-fade utility.
   Inner pages can link this file and reuse .site-header / .site-footer /
   .btn / .field / .seg / .img-fade without the home-page CSS (home-2026.css).

   BRAND: "night charging". Deep navy (--night) with one accent, charge-lime (--volt),
   on cool paper neutrals. Display: Sora. Text: Hanken Grotesk. Meta/figures: IBM Plex Mono.
   All three are self-hosted (assets/fonts), so there are no third-party font requests.

   Contrast (WCAG AA, computed): ink on bg 16.8:1 · muted on bg 6.7:1 · muted on white 7.3:1 ·
   night-dim on night 11.2:1 · night-dim on night-3 8.9:1 · lime on night 15.6:1 ·
   night on lime 15.6:1 · volt-ink on white 8.3:1 · focus blue on bg 6.7:1 ·
   danger on white 7.5:1 · danger-night on night 9.6:1 · control borders 4.2:1+ (needs 3:1)

   READABILITY + MICRO-SPACING TOKENS (standing rules for every page that links this file)
   Type scale, fluid (390px -> 1440px):
     --t-display 40 -> 72 · --t-h2 30 -> 52 · --t-h3 20 -> 24
     --t-lede    17 -> 19  (lead paragraph, 18px+ on desktop)
     --t-body    16 -> 17  (paragraphs, inputs, descriptions; never below 16)
     --t-small   15 -> 16  (nav, buttons, table cells, notes, "sample" lines; never below 15)
     --t-meta    14 -> 15  (mono caps labels, eyebrows, badges, table heads; never below 14)
   Nothing renders below 14px. Line-height: body 1.6, small 1.5, headings 1.05-1.2.
   Letter-spacing: display -.04em, h2 -.03em, h3 -.02em, mono/caps labels +.08em.
   Measure: paragraphs cap at --measure (66ch); lede at 54ch.
   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) · list rows 16-24
     table cells 12-16 · 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, kW, counts) use tabular-nums so columns and baselines line up.

/* =========================================================
   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 img-zoom"><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
     fade-in       .js-motion + .fx-img.is-wait opacity fade once the file is fetched AND decoded (JS pre-decodes
                   lazy photos ahead of the viewport; no blur filter; with no JS or reduced motion the photo is just there)
     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)
   .img-zoom  (add to the wrapper)  hover zoom to 1.04 inside the clipped picture, fine pointers,
              motion allowed only; never changes layout
   --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. Reduced motion: no fade-in, no zoom, no Ken Burns, photo is static.
