/* ==========================================================================
   Dimo Softwares — Shared Design System (tokens + primitives)

   Calm, neutral, precise. The UI is almost entirely greyscale; each service's
   accent (--primary-rgb) is reserved for the primary action, focus rings,
   selection and small active indicators. No glows, no ambient gradients, no
   glass: depth comes from three surface steps and hairline borders.

   Layers (both themes):
     page      --color-bg-dark        the canvas
     surface   --color-surface        cards, panels, sidebars
     raised    --color-raised         popovers, menus, sheets
     well      --sunken               inputs, code, recessed plates

   and clears 4.5:1 as text. Storage keeps a golden fill with dark text and a
   separate darker ink.

/* ── Brand lockups on the light theme ───────────────────────────────────────
   Every logo PNG is authored for a dark UI: near-white wordmarks with neon
   glyphs. On the light theme they wash out (the plain Dimo mark measures
   1.12:1 on white — effectively invisible).

   `filter: invert(1)` was the previous fix and only ever worked for the
   greyscale mark: inverting a coloured lockup rotates its hue 180°, so the cyan
   Agents logo came out orange and Storage's yellow came out blue.

   Instead each lockup keeps its hue and is darkened (with a touch of extra
   saturation for the already-dark magenta) until the wordmark clears 4.5:1 on
   white. Values were measured against each PNG's median visible pixel, not
   guessed — re-measure if the artwork is replaced. */

/* ── Responsive-visibility guard ────────────────────────────────────────────
   This file is loaded AFTER tailwind.css, so any component class that declares
   its own `display` (.btn, .icon-btn, .chip, .side-link, .footer-links …) beats
   a Tailwind `hidden` utility at equal specificity — last one wins.

   That silently broke every responsive hide: `class="icon-btn md:hidden"` still
   computed `display: flex` at 1440px, so the mobile hamburger rendered on
   desktop next to the full nav, and `hidden lg:inline-flex chip` header chips
   stayed visible on mobile and pushed the header 8px past the viewport.

   Re-asserting the responsive `hidden` variants here — at the end of the
   cascade, each inside its own breakpoint — hands visibility back to the
   utilities while components keep owning their layout. Scoped deliberately to
   the `min-width` variants: a bare `.hidden` is NOT re-declared, because
   `class="hidden md:flex"` legitimately relies on the later `md:flex` winning.
   Breakpoints mirror Tailwind's defaults. */
