+# FLXN theme system
+
+A theme is a self-contained folder under `src/themes/<id>/` containing exactly
+two files. Themes are auto-discovered via `import.meta.glob` — adding a theme
+is adding a folder, removing one is deleting it. No shared file is ever edited.
+
+```
+src/themes/
+  <id>/
+    manifest.ts   # metadata + optional JS-side Mantine override
+    theme.css     # all visual work, scoped under [data-theme="<id>"]
+```
+
+Activation: the provider sets `data-theme="<id>"` on `<html>` (mirrored to
+localStorage `flxn-theme` for the pre-hydration script in `__root.tsx`).
+The preference is stored per-user in SuperTokens metadata (`metadata.theme`).
+
+## manifest.ts
+
+```ts
+import { msg } from "@lingui/core/macro";
+import type { ThemeManifest } from "../types";
+
+const manifest: ThemeManifest = {
+  id: "comic",                       // MUST equal the folder name
+  label: msg`Comic`,                 // i18n — always msg``
+  colorSchemes: "both",              // or "light" / "dark" to force a scheme
+  fontLinks: [                       // injected only while theme is active;
+    "https://fonts.googleapis.com/css2?family=Bangers&display=swap",
+  ],                                 // browsers fetch font files lazily
+  chromeColors: {                    // browser-chrome theme-color meta
+    light: { base: "#fde047", dimmed: "#ca8a04" },
+    dark: { base: "#1c1917", dimmed: "#0c0a09" },
+  },
+  mantine: {                         // optional Mantine override, merged onto
+    defaultRadius: "xs",             // the base theme via mergeThemeOverrides.
+    components: { /* defaultProps, vars, … */ },
+  },
+};
+
+export default manifest;
+```
+
+Rules:
+- `label` must use `msg` from `@lingui/core/macro` (never raw strings, never
+  global `t`). Translations are handled centrally afterwards.
+- Prefer doing visual work in `theme.css`; use `mantine` only for things CSS
+  cannot express (defaultProps, per-component `vars` resolvers).
+
+## Accent color (REQUIRED)
+
+The user picks an accent (blue, red, green, yellow, grape, orange, pink,
+lime) and EVERY theme must honor it — there is no way to lock the accent.
+
+- Primary/interactive styling must derive from the primary aliases
+  (`--mantine-primary-color-filled`, `-light`, `-6`, …) or from the accent
+  ramps generically — never from one hardcoded brand hue.
+- A theme MAY retune all eight accent ramps (`--mantine-color-blue-*`,
+  `--mantine-color-red-*`, …) to fit its world — e.g. neon versions, pastel
+  versions, phosphor-tinted versions — as long as the eight choices remain
+  visually distinct. Retuning shades is encouraged; ignoring the choice is
+  forbidden.
+- Theme-flavor decoration may still use fixed hues (a comic's halftone tint,
+  a blueprint's grid ink), but anything that reads as "the accent" —
+  filled buttons, active tabs/nav, focus rings, selection — follows the user.
+
+## light-dark() trap
+
+Never use `light-dark()` in a declaration whose selector matches `<html>`
+(any `[data-theme=…]` token block): postcss-preset-mantine rewrites it into
+a descendant selector that can never match the root element, so the dark
+branch silently dies. Use the explicit compound scheme selectors (shape 2)
+instead. Inside descendant rules (`[data-theme] .mantine-Button-root`)
+light-dark() is fine.
+
+## theme.css — selector templates (specificity is load-bearing)
+
+Mantine emits its variables from a runtime `<style>` tag that appears AFTER
+our bundled CSS, so theme overrides must WIN ON SPECIFICITY, not order. Use
+these exact selector shapes:
+
+```css
+/* 1. Tokens for any scheme — (0,2,0), beats Mantine's :root block */
+[data-theme="comic"][data-theme] {
+  --mantine-radius-default: 0;
+  --mantine-font-family: "Comic Neue", cursive;
+}
+
+/* 2. Per-scheme tokens — (0,3,0), beats Mantine's :root[scheme] blocks */
+[data-theme="comic"][data-theme][data-mantine-color-scheme="light"] {
+  --mantine-color-body: #fef9c3;
+}
+[data-theme="comic"][data-theme][data-mantine-color-scheme="dark"] {
+  --mantine-color-body: #1c1917;
+}
+
+/* 3. Component restyles — descendant selectors on static classes */
+[data-theme="comic"] .mantine-Button-root {
+  border: 3px solid #000;
+  box-shadow: 4px 4px 0 #000;
+}
+
+/* 4. Full-page decorations (scanlines, halftone, grain) */
+[data-theme="comic"] body::before {
+  content: "";
+  position: fixed;
+  inset: 0;
+  z-index: 9998;           /* above content, below --mantine-z-index-max */
+  pointer-events: none;
+  /* embed textures as data-URI SVG/gradients — no external requests */
+}
+```
+
+The doubled `[data-theme]` attribute is intentional (specificity bump).
+Still never use `html[data-theme]` or `:root[data-theme]` — the doubled
+attribute form matches `<html>` at higher specificity and stays portable.
+
+## Previews (no per-theme work required)
+
+The settings picker renders each theme in its own sandboxed same-origin
+srcdoc iframe (`theme-preview.tsx`): the iframe's `<html>` carries the
+theme's `data-theme`/`data-mantine-color-scheme`, its head gets a snapshot
+of the app's real stylesheets, the theme's `fontLinks`, and the theme's
+Mantine JS-side variables computed with Mantine's own resolver from the
+same `baseTheme` + `manifest.mantine` + accent merge the live provider
+performs. Previews are therefore 1:1 with the active theme by construction
+— fonts, textures, html/body-level rules and all — and nothing bleeds
+between the active theme and a preview. There is no preview variable
+contract to maintain, and `--mantine-primary-color-*` must still never be
+pinned by a theme (the user's accent must show through everywhere,
+previews included).
+
+## What you can override (cheat sheet)
+
+Mantine components style themselves from CSS variables — overriding variables
+retints the whole app with zero React work.
+
+- Palettes: `--mantine-color-<name>-<0..9>` and per-color variant vars
+  (`-filled`, `-filled-hover`, `-light`, `-light-hover`, `-light-color`,
+  `-outline`, `-outline-hover`, `-text`); primary aliases
+  `--mantine-primary-color-{0..9,filled,filled-hover,light,light-hover,light-color,contrast}`.
+- Scheme-dependent semantics (define per scheme, selector 2):
+  `--mantine-color-body`, `-text`, `-dimmed`, `-bright`, `-anchor`, `-error`,
+  `-placeholder`, `-default`, `-default-hover`, `-default-color`,
+  `-default-border`.
+- Shape: `--mantine-radius-{xs..xl}`, `--mantine-radius-default`.
+- Elevation: `--mantine-shadow-{xs..xl}` (composite strings — neobrutalism
+  uses `4px 4px 0 #000`, glass uses soft large blurs).
+- Type: `--mantine-font-family{,-monospace,-headings}`,
+  `--mantine-font-size-{xs..xl}`, `--mantine-h{1..6}-font-size/-line-height/-font-weight`,
+  `--mantine-heading-font-weight`, `--mantine-line-height{,-xs..xl}`.
+- Spacing: `--mantine-spacing-{xs..xl}` (be conservative — layout shifts).
+- App tokens (see `base.css`): `--flxn-gold/-silver/-bronze`,
+  `--flxn-toast-success/-error`, `--flxn-podium-{1,2,3}-{bg,border,label}`,
+  `--flxn-showcase-bg`, `--flxn-overlay`, `--flxn-dotgrid-color`,
+  `--flxn-pop-shadow`. Override these with selector 1/2 shapes (they beat
+  base.css's `:root` on specificity).
+
+Static classes for restyling (most-used components in this app): Button,
+ActionIcon, Paper, Card, TextInput/Input (`.mantine-Input-input`), Select,
+Badge, Tabs (`-list`, `-tab`), SegmentedControl (`-root`, `-indicator`,
+`-label`), Modal (`-content`, `-header`), Avatar, ThemeIcon, Skeleton,
+Loader, Alert, Tooltip, Popover (`-dropdown`), Switch, Checkbox, Progress,
+PinInput, NavLink, Notification, AppShell (`-header`, `-navbar`, `-main`),
+Divider, Indicator — as `.mantine-<Component>-<part>`. State comes as data
+attributes: `[data-variant]`, `[data-active]`, `[data-disabled]`, etc.
+
+Custom app components (sheet drawers, nav tiles, list rows, carousels) are
+built on the same `--mantine-*`/`--flxn-*` variables and follow automatically.
+
+## App component hooks
+
+Stable classes/tokens for custom components (defaults live in
+`src/themes/hooks.css`; themes override under `[data-theme]` scopes — theme
+files load after hooks.css, so equal-specificity rules win by order):
+
+- `.flxn-tabs` / `.flxn-tab` (+`[data-active]`) / `.flxn-tabs-indicator` —
+  the swipeable tab strip used on profile/tournament pages. Restyle these so
+  tabs belong to the theme (block active states, underlines, boxed tabs…).
+  TWO STATES: resting (mid-page) must stay FLAT — transparent background,
+  no strip chrome, blending into the page; the docked treatment (background,
+  rules, shadows, textures) goes on `.flxn-tabs[data-stuck]` only, which the
+  component sets while the strip is pinned to the top. hooks.css provides
+  the transition between states. Tab/indicator styling must stay legible
+  over the bare page background in the resting state.
+  STACKING: the indicator is Mantine FloatingIndicator — absolutely
+  positioned, so it would paint OVER the static tab labels; hooks.css
+  lifts `.flxn-tab` (`position: relative; z-index: 1`) so labels always
+  render on top. Never z-index the indicator above 1 or an opaque fill
+  swallows the labels.
+  PAIRING RULE: an accent-filled indicator pill/block (or accent-filled
+  `.flxn-tab[data-active]`) MUST pair its label with `--flxn-on-accent`
+  (black/white computed from the actual cascaded fill — safe under CSS
+  ramp retunes, unlike `--mantine-primary-color-contrast`, which Mantine
+  computes from the JS theme colors and can disagree with a CSS-retuned
+  fill). Never accent text over an accent fill. If the indicator is an
+  underline/rule, accent text is fine.
+  NO glow/soft shadows on `.flxn-tabs-indicator` (owner preference): a
+  clean underline or flat plate only. Rich active-tab chrome (wells,
+  engraving, plates beyond the indicator) belongs under
+  `.flxn-tabs[data-stuck]` like the strip chrome — resting tabs stay flat.
+- `.flxn-tile` / `.flxn-tile-icon` — home/tournament nav grid tiles. Treat
+  like Card/Paper: give them the theme's surface language.
+- (retired) `.flxn-see-all` — "see all" actions are plain Mantine subtle
+  Buttons now, accent-driven by design. Do NOT reintroduce per-theme chip
+  styling for them; they inherit only your generic Button treatment.
+- `.flxn-bracket-card` — the small dense match cards inside the bracket
+  view (they are Mantine Cards). Exclude them from heavy Card decorations
+  (valances, ornaments) that suit full-width cards but overwhelm bracket
+  density.
+- `.flxn-match-card` + `.flxn-reaction-row` — a match card with a reaction
+  tray tucked underneath (tray = full border + full radius, hidden top edge).
+  Keep the pair reading as one construction in your theme: matching borders
+  and backgrounds, tray background contrasting subtly with the card.
+- `.flxn-badge-tile` — badge grid tile motion hook; tile shape follows
+  `--flxn-badge-radius` (default 12px).
+- `.flxn-avatar-frame` + `--flxn-avatar-radius` (default `50%`) +
+  `--flxn-avatar-border` (default `1px solid` default-border) — avatars.
+  The frame owns the avatar's SINGLE border via the token; NEVER put a
+  border/outline on `.mantine-Avatar-root` (hooks.css force-strips it —
+  doing so doubles every ring). The frame is a plain Box, so generic
+  Paper restyles don't reach it; square-language themes set the radius
+  to 0–4px and restyle via the two tokens (plus `.flxn-avatar-frame` for
+  anything richer, e.g. shadows/bezels).
+- `.flxn-tile-icon` — keep icons FLAT: tint the glyph (color), no
+  background plates/borders/padding behind it. A plate is only justified
+  when the theme's whole language demands it (rare); default to flat.
+
+## Hard rules
+
+- EVERYTHING scoped under `[data-theme="<id>"]`. Zero unscoped selectors —
+  a theme must be inert when inactive.
+- Support both schemes unless the design genuinely demands one; then set
+  `colorSchemes: "light" | "dark"` (the engine forces it).
+- Accessibility gates:
+  - Wrap flicker/pulse/marquee animations in
+    `@media (prefers-reduced-motion: no-preference) { … }`.
+  - Give `backdrop-filter` surfaces a solid fallback via
+    `@supports not (backdrop-filter: blur(1px))` and respect
+    `@media (prefers-reduced-transparency: reduce)`.
+  - Keep real borders on interactive elements (forced-colors mode strips
+    shadows/gradients).
+  - Body text must stay ≥ 4.5:1 contrast in every supported scheme.
+  - Mantine hardcodes WHITE on `[data-combobox-selected]` (Select options)
+    and `theme.autoContrast` does not reach it. hooks.css fixes this
+    globally with `--flxn-on-accent`; if your theme overrides the
+    selected-option styling, pair the fill with an explicit legible
+    on-color yourself.
+  - Any `background-clip: text` gradient text needs a
+    `@media (forced-colors: active)` fallback (`background-image: none;
+    color: CanvasText`) or headings vanish in forced-colors mode.
+  - Re-flavored `.flxn-press` transforms MUST be wrapped in
+    `@media (prefers-reduced-motion: no-preference)` — theme selectors
+    outrank the global reduce kill in the provider.
+  - Placeholder text ≥3:1 and dimmed text ≥4.5:1 against the body color.
+  - Text must never share its hue with the fill directly behind it
+    (accent-on-accent, gold-on-gold…). Accent fills pair with
+    `--flxn-on-accent` (base.css token: black/white picked from the actual
+    cascaded `--mantine-primary-color-filled`); accent washes pair with
+    `--mantine-primary-color-light-color`; accent text needs a neutral
+    backing. Applies to tab indicators, SegmentedControl, active NavLinks,
+    badges, chips — anywhere a label sits on a colored plate.
+- Performance gates:
+  - Never animate variables on `:root`/`html` — animate leaf elements.
+  - At most 1–2 full-viewport overlay pseudo-elements, `pointer-events: none`.
+  - Limit `backdrop-filter` to a handful of surfaces; never animate blur.
+  - Textures/assets as data-URIs inside theme.css; no network requests.
+- Don't break layout: the app is a mobile-first PWA (AppShell header +
+  navbar). Radius/borders/shadows/fonts are fair game; avoid changing
+  spacing scales drastically or adding outer margins to shell parts.
+- The press feedback (`.flxn-press`, scale on :active) is global; themes may
+  re-flavor it, e.g. `[data-theme="brutal"] .flxn-press:active { transform:
+  translate(4px, 4px); }`.
+- i18n: manifest strings via `msg` only. Do NOT run lingui extract/compile —
+  handled centrally.
+
+## Verifying a theme
+
+`bun x tsc --noEmit` must pass. Do not run the dev server; visual QA happens
+centrally after all themes land.
