/* [2026-07-27] ADDED — Indic script webfonts for regional-language interviews.
 *
 * WHY: the global rule in assets/css/portal.css was `font-family: Manrope !important`
 * with no fallback family. Manrope contains ZERO glyphs for every Indic script
 * (verified: 678 glyphs, 0 in U+0B80-0BFF), and the bundled Poppins has 0 Tamil too.
 * So Tamil/Bengali/... transcript text fell through to whatever font the rendering
 * machine happened to have installed. That machine is frequently NOT a laptop — it is
 * the 100ms "beam" headless-browser recorder that renders components/Pages/FullBeam.jsx
 * (-> LiveKit/BeamTranscriptPanel.jsx) and burns the transcript panel into the MP4.
 * Whatever that container lacked became permanent tofu boxes in the recording.
 *
 * Covers the 8 languages in realtime-support-system/language.py `regional_languages`:
 * Bengali, Tamil, Telugu, Gujarati, Kannada, Malayalam, Marathi (Devanagari),
 * Punjabi (Gurmukhi).
 *
 * NOTES FOR FUTURE MAINTAINERS:
 * - This file and its .woff2 files both live under `public/`, and it is loaded by a <link> in
 *   public/index.html — deliberately NOT imported from src/. Two independent reasons:
 *     1. webpack.config.js:85-87 sends every font matched under src/ through
 *        `type: 'asset/inline'` (base64-embedded into the bundle). Inlining these would add
 *        ~730KB to the main bundle for EVERY user and would defeat the `unicode-range` gating
 *        below, because a base64 data: URI is always downloaded.
 *     2. css-loader resolves root-relative `url(/...)` in stylesheets imported from src/ and
 *        fails the build: "Module not found: Can't resolve '/fonts/noto/...'". (Verified — an
 *        earlier attempt to import this from App.js broke `npm run build`.)
 *   Files in public/ are copied verbatim by CopyPlugin (webpack.config.js:129-142) and served
 *   by devServer.static (:163), so the browser gets real, separately-fetchable URLs.
 * - Each `unicode-range` is Google Fonts' own published range for that subset, copied
 *   verbatim. The browser downloads a family ONLY if the page actually contains a
 *   character in its range, so an English interview downloads ZERO bytes from this file.
 * - The shared symbols in these ranges (U+20B9 rupee, U+200C-200D ZWJ/ZWNJ) are already
 *   covered by Manrope's latin/latin-ext subsets. Manrope is first in the font stack, so
 *   it still wins for those on English pages — no accidental Noto download. They are kept
 *   in the Indic ranges deliberately: ZWJ/ZWNJ must resolve to the SAME font as the
 *   surrounding Indic run or the browser splits the shaping run and conjunct
 *   formation/suppression breaks.
 * - These are variable fonts (wght axis 100-900, verified), so one file per script serves
 *   every weight, including the <b> speaker label in the transcript panel.
 * - Fail-open by construction: if a file 404s or the network drops, the browser skips the
 *   family and falls through to the next one in the stack — i.e. exactly today's behavior.
 *   Kill switch: remove the `<link rel="stylesheet" href="/fonts/indic.css">` in public/index.html.
