+/* The SCOPED 7.css build: postcss-prefix-selector rewrote every selector to
+   `.win7` (root rules) or `.win7 <sel>` (the rest), so the whole framework is
+   inert until SettingsService.applySkin puts that class on <html>. All 61
+   icons are data URIs, so nothing needs copying into assets — and NOT the
+   `7.inline.css` build, which flattens away the --w7-* vars the dark palette
+   below depends on. The deep path is required: 7.css ships no `exports` map
+   and Tailwind's resolver only reads `style`/`mainFields`, so a bare
+   `@import "7.css"` finds no entry. */

+
+/* ==========================================================================
+   Windows 7 skin — SettingsService.applySkin puts `.win7` on <html>
+   ==========================================================================
+
+   Three tiers, and the split matters:
+
+   - `@layer skin` (the 7.css import at the top of this file) owns the
+     CONTROLS: buttons, inputs, tabs, progress bars, tree views, the Aero
+     title bar. It sits ABOVE `utilities`, so a bare `button` rule in 7.css
+     beats `.rounded-md` on that same button. That inversion is the whole
+     trick — it restyles ~1900 inline utility classes with no template edits.
+   - This unlayered section owns the BRIDGE: it re-points the app's own
+     semantic tokens at Win7 values, so utilities Tailwind still controls
+     (bg-card, border-border, text-muted-foreground) also come out
+     Win7-correct. It adds NO new tokens on purpose — a new colour token
+     would need a matching `--color-*` line in `@theme inline`.
+   - `@layer skinfix` (last, above `skin`) hands individual properties BACK to
+     the utilities layer with `revert-layer`, for the places where 7.css's
+     Win7-dialog metrics are wrong for this app.
+
+   WARNING for future edits: because `skin` outranks `utilities`, any Tailwind
+   utility added later to a <button>, <input>, <select>, <textarea> or <table>
+   silently loses under this skin. `skinfix` is the only place to fix that.
+
+   Specificity notes — the blocks below must beat the token blocks above:
+     :root.win7                    (0,2,0) beats base :root          (0,1,0)
+     :root.win7[data-theme='dark'] (0,3,0) beats :root[data-theme=…] (0,2,0)
+                                   and ties the darker-tone block    (0,3,0),
+                                   winning on source order (it is last).
+   The accent formula blocks are deliberately NOT overridden: they only set
+   --primary/--ring/--cursor-tint, and letting them through is what makes the
+   accent picker recolour the Aero chrome — authentic, Win7 shipped exactly
+   that ("Window Color" personalization). */
+
+/* Segoe UI is not on macOS/Linux and is not redistributable. Noto Sans is the
+   substitute 7.css itself names in its --w7-font fallback stack. Vendored
+   (OFL-1.1) from @fontsource/noto-sans@5.3.0, files/noto-sans-latin-{400,700}
+   -normal.woff2 -> ./fonts/, i.e. INSIDE this skin: the font exists only for
+   the Win7 look, and keeping it here means the url() below stays relative to
+   this file wherever the skin folder moves. (It used to sit at ui/src/fonts/
+   next to the old single stylesheet — splitting this file out rebased the
+   url() three directories deeper and would have silently 404'd the font.)
+   Vendored rather than @imported from node_modules because Tailwind inlines
+   imported CSS, which would leave @fontsource's relative url() rebased against
+   the wrong directory. They live under src/ (not public/) so esbuild emits them
+   as hashed assets and rewrites the url() — a public/ path is not resolvable at

+/* ==========================================================================
+   shadlike skin — the modern, shadcn-style look
+   ==========================================================================
+
+   Intentionally near-empty, and that is not an oversight.
+
+   This skin IS the shared foundation: the OKLCH token system, `@theme inline`,
+   the data-text interface sizes and the accent axis all live in ui/src/styles.css
+   because both skins consume them, and everything else the modern look needs is
+   a Tailwind utility written inline in its templates. There is no third-party
+   framework to bridge and no cascade inversion to undo, so there is simply
+   nothing left for a skin-level stylesheet to say.
+
+   Compare app/skins/7like/7like.css, which is 630 lines: all of it exists to
+   import 7.css above `utilities`, re-point the app's semantic tokens at Win7
+   values, and hand individual properties back where 7.css's dialog metrics are
+   wrong for this app.
+
+   This file exists so the folder is self-contained and symmetrical with the
+   other skin — modern-only rules that should not leak into the win7 cascade
+   have a home here. Rules that BOTH skins need belong in ui/src/styles.css
+   instead; anything added here is dead weight under .win7.
+
+   Scoping note: 7like scopes itself with the `.win7` class that 7.scoped.css
+   requires. This skin is the default (no marker class), so any rule added here
+   must NOT be written so broadly that it also matches under .win7 — prefer
+   scoping to the component, not to bare elements. */

-/* ==========================================================================
-   Windows 7 skin — SettingsService.applySkin puts `.win7` on <html>
-   ==========================================================================
-
-   Three tiers, and the split matters:
-
-   - `@layer skin` (the 7.css import at the top of this file) owns the
-     CONTROLS: buttons, inputs, tabs, progress bars, tree views, the Aero
-     title bar. It sits ABOVE `utilities`, so a bare `button` rule in 7.css
-     beats `.rounded-md` on that same button. That inversion is the whole
-     trick — it restyles ~1900 inline utility classes with no template edits.
-   - This unlayered section owns the BRIDGE: it re-points the app's own
-     semantic tokens at Win7 values, so utilities Tailwind still controls
-     (bg-card, border-border, text-muted-foreground) also come out
-     Win7-correct. It adds NO new tokens on purpose — a new colour token
-     would need a matching `--color-*` line in `@theme inline`.
-   - `@layer skinfix` (last, above `skin`) hands individual properties BACK to
-     the utilities layer with `revert-layer`, for the places where 7.css's
-     Win7-dialog metrics are wrong for this app.
-
-   WARNING for future edits: because `skin` outranks `utilities`, any Tailwind
-   utility added later to a <button>, <input>, <select>, <textarea> or <table>
-   silently loses under this skin. `skinfix` is the only place to fix that.
-
-   Specificity notes — the blocks below must beat the token blocks above:
-     :root.win7                    (0,2,0) beats base :root          (0,1,0)
-     :root.win7[data-theme='dark'] (0,3,0) beats :root[data-theme=…] (0,2,0)
-                                   and ties the darker-tone block    (0,3,0),
-                                   winning on source order (it is last).
-   The accent formula blocks are deliberately NOT overridden: they only set
-   --primary/--ring/--cursor-tint, and letting them through is what makes the
-   accent picker recolour the Aero chrome — authentic, Win7 shipped exactly
-   that ("Window Color" personalization). */

-  /* ---- Window frame ----
-     The native window is transparent (chromeOptions in src/bun/windows.ts), and
-     nothing but .window may paint an opaque surface — that is what lets the 6px
-     corner radius actually be transparent at the corners. That invariant is NOT
-     free: html/body paint an opaque background unlayered, and had to be reset
-     to transparent for .win7 (see the rule above @layer skin). Anything else
-     that paints full-bleed will fill the corners the same way.
-     NO drop shadow, by request: 7.css's `2px 2px 10px 1px #000000b3` needed a
-     margin gutter to fall into and still read heavy against a real desktop, so
-     the frame keeps only the inset 1px glass highlight from that shorthand
-     (dropping the whole box-shadow would lose the highlight too — it lives in
-     the same declaration). No shadow -> no gutter -> full-bleed 100vh.
-     Keyed on `w7-frame` — the app hook the three window ROOTS carry — never on
-     bare .window: on any other .window (dialogs, demos) this sizing is
-     nonsense and 7.css's own shadow is fine. */

-     The radius is declared three times in 7.css — on .window and on both the
