/* Dashboard tools — 3 separate real pages (restructured 2026-09-10, 2nd
   pass, replacing an earlier single-page-with-inline-toggle design):
     1. #dashboard-page — the banner's target, just a "Select a view"
        chooser (.rd-view-switch/.rd-select below) that navigates away
        on selection. No other content.
     2. #registration-dashboard-page (rd-* classes) — the gated, logged-
        in-member version of the old standalone
        student-registration-dashboard repo (kept running unchanged, no
        login, for outside/WhatsApp sharing — see
        js/registration-dashboard.js's own header comment). Table/badge/
        summary values ported near-verbatim from that repo's style.css;
        the card/form-input values mirror support-requests.css's own
        conventions for consistency with the rest of this app.
     3. #seminar-list-page (sl-* classes, own section further down this
        file) — the video-editing tracker ported from the standalone
        SeminarList repo (Google Sheet via Apps Script, unchanged) — see
        js/seminar-list.js. Its own full dark/gold page design, not
        reskinned to match #2's light/purple look. */

/* Same root-cause fix as support-requests.css's own (2026-09-09) — both
   #dashboard-page and #registration-dashboard-page share the identical
   <header>+<main> markup, so both have the same latent risk from
   global.css's .page-section.active flex-centering (shrinks/re-centers
   <main> when its content is short/narrow — #dashboard-page's chooser is
   about as short/narrow as content gets). */

   Seminar List page (#seminar-list-page — split into its own real

   SeminarList repo's own index.html/code.gs (Google Sheet via Apps
   Script, unchanged — see js/seminar-list.js's own header comment).

   Per Balaji: this needs to be its own full page with its own design,
   not the Registration Dashboard's light/purple theme, and not just a
   dark card floating inside a light page either — so #seminar-list-page
   itself IS the dark/gold theme (it carries the `.sl-theme` class in
   index.html), full page background included. All `--sl-*` custom
   properties are scoped to `.sl-theme` rather than `:root`/`body` so
   they can't leak into the rest of this app's global styling.

/* ------------------------------------------------------------------
   Birthday List (#birthday-list-page) & Grade Wise List
   (#grade-list-page) pages — added 2026-09-12. Two more tools on the
   same #dashboard-page chooser as Registration Dashboard, deliberately
   reusing that page's own rd-* rules above rather than inventing a
   fourth/fifth visual language — same header/main markup, same
   .rd-controls/.rd-select/.rd-table-wrap/.rd-badge/.rd-actions-row/
   .rd-copy-btn/.rd-no-data classes, just extending each existing
   selector's scope to these two new page ids. See js/birthday-list.js
   and js/grade-list.js.
