     the cards. In fact, you could probably reduce those box shadows
     quite a bit. At least they shouldn't span the entire edge of
     the card. Just a subtle bit in the corner.").
     The prior `--edge-light-warm` / `--edge-light-cool` tokens were
     complete box-shadow declarations with offsets that spanned the
     entire bottom-left + top-right edges of every chip. They've
     been retired. The replacement is a pair of plain RGBA colors
     consumed by radial-gradient layers in the chip's BACKGROUND
     (border-box-clipped) — see `.glass-panel` below — so the
     warm/cool light response now reads as a corner-concentrated
     highlight ON the chip's 1px border, not as an outer drop
     shadow extending into the body gradient.
     The `--chip-border-base` is a faint diagonal white tint that
     paints under the corner gradients so the rest of the rim isn't
     completely invisible (gives the chip a sensible edge even far
     from either light source).

     Two intensity tiers (2026-06-04 refinement, operator feedback
     after the original tokens went out — "reduce the vibrancy of
     the border gradients on the cards"):

       1. `--corner-light-{warm,cool}` (full intensity) — used by
          the floating chrome chips (sidebar nav, top header) where
          the catch-light SHOULD be the primary visual cue that the
          element is a distinct floating surface responding to the
          background light sources. Consumed via inline `boxShadow`
          in `components/Layout.js` and `components/ui/TopSearchBar.js`.

       2. `--corner-light-{warm,cool}-subtle` — used by `.glass-panel`
          and `.glass-panel-strong` (data cards: stat cards, deck
          cards, list cards, modals, dropdowns). These surfaces are
          numerous and tile densely; at full intensity the catch
          lights compete with the chrome and overwhelm the page.
          Roughly 55% of the full-intensity alpha. */

/* Nav-item hover/focus — third pass 2026-06-04. Operator feedback
   after the spotlight landed (PR #110): "remove the shading around
   the hover that makes it feel like it's floating" + "the gradient
   is a little too bold." Two changes from the prior pass:
   1) Dropped the base background-color tint on the host. With the
      bg-tint gone, the item no longer reads as a "floating chip"
      against the sidebar — just the radial spotlight remains,
      which feels like light pooling under the cursor rather than
      a state-color rectangle. Text color shift to --text-primary
      stays as the secondary affordance (and for AA contrast on the
      label).
   2) Toned down the radial-gradient alphas. Light: 35%/18% → 22%/
      10%. Dark: 40%/22% → 26%/12%. Same shape, gentler glow. */
/* Hover/focus also surfaces a subtle 1px ember border so the
   hit-target of the chip is unambiguous even when the cursor is
   near an edge (operator feedback after PR #111: the spotlight-only
   hover hid the exact bounds of the interactive surface). The
   border is 28% alpha — distinctly visible but lighter than the
   active state's full-saturation ember border so the two states
   remain readable side-by-side (hover < active). Implemented via
   box-shadow inset rather than border: 1px to avoid the 1px layout
   shift a real border would cause when toggling on hover. */

/* ============================================================

   <GlassSurface> primitive for every flat container. Added by
   glass-body-panels PR after PR #96 left admin/settings/dashboard
   body cards on solid --bg-secondary.

   Composition matches <GlassSurface tint="mid" rim="subtle"
   elevation="ambient" blur="mid">. Always pair with rounded-*
   from Tailwind (the class itself doesn't set border-radius
   because consumers vary between rounded-xl and rounded-2xl).
   ============================================================ */
/* IMPORTANT — composing rim + elevation tokens correctly.
   The --rim-light-outer / --rim-light-inner / --elevation-* tokens are
   COMPLETE box-shadow declarations (each contains offset/spread/color or
   the `inset` keyword), not raw color values. They are designed to be
   *chained into a single box-shadow*, exactly the way <GlassSurface>'s
   `boxShadow: shadowParts.join(', ')` composes them. Do NOT use
   `border: 1px solid var(--rim-light-outer)` — that parses
   `border-width` from the first token of the shadow string ("0"), which
   yields a 0px border. And do NOT wrap --rim-light-inner in another
   `inset 0 1px 0` prefix — the token already contains its own `inset`
   keyword, so wrapping produces invalid syntax that the browser drops
   the entire box-shadow declaration for. PR #98 had both mistakes,
   which is why the panels in PR #97/#98 had neither visible border nor
   drop shadow despite the backdrop-filter being correct.

   Backdrop-filter quirks with Next.js 16's Lightning CSS (also relevant):
   1) `backdrop-filter: blur(var(--X)) saturate(var(--Y))` is silently
      stripped (var() inside function args breaks the optimizer). Use
      LITERAL values here. Tokens stay in :root for the <GlassSurface>
      JSX primitive which sets backdropFilter via inline style.
   2) Writing both `backdrop-filter` AND `-webkit-backdrop-filter` with
      identical values triggers Lightning CSS's buggy de-dup; it keeps
      only the `-webkit-` form which modern browsers ignore. Write only
      the unprefixed form; Lightning CSS's autoprefixer adds the prefix
      per browserslist (ios_saf <18 still needs it). */
/* Glass panels — the canonical floating-chrome surface. 2026-06-04
   corner-border pass (refines the prior two-light-source pass):
   the warm + cool light response now paints on the chip's 1px
   border using the multi-layer background + transparent-border
   technique:
     1. linear-gradient(surface, surface) padding-box — the chip's
        translucent fill, clipped to the padding box so it doesn't
        cover the 1px border ring.
     2. radial-gradient(at 0% 100%, warm) border-box — warm corner
        catch-light, anchored at the chip's bottom-left.
     3. radial-gradient(at 100% 0%, cool) border-box — cool corner
        catch-light, anchored at the chip's top-right.
     4. --chip-border-base border-box — faint diagonal white tint
        under the corner gradients so the rest of the rim isn't
        invisible (gives the chip a sensible edge far from either
        light source).
   The `border: 1px solid transparent` is what exposes those
   border-box-clipped gradient layers as the visible rim.
   Drop-shadow stack is now just rim-light-inner + elevation —
   the directional warm/cool outer glows are gone per operator
   feedback ("reduce those box shadows quite a bit").

   `.glass-panel*` uses the SUBTLE corner-light variants (about 55%
   of the full-intensity alpha used by the floating chrome chips in
   Layout / TopSearchBar). Data cards tile densely, so at full
   intensity the catch lights compete with the chrome and overwhelm
   the page (2026-06-04 operator feedback: "reduce the vibrancy of
   the border gradients on the cards"). */
