/* StudyDaily public site — the whole visual system.
 *
 * DIRECTION: THE TRACE. Circling, underlining, highlighting: that is the gesture
 * of the person studying. StudyDaily is a revision app, so the marks are not a
 * skin laid over the product — they are what the user does. Here the mark
 * arrives DURING reading: a highlighter wipes in as its phrase enters view, a
 * thread is drawn between two things that belong together.
 *
 * ============================================================================
 * THE RULE THAT DECIDES WHERE A MARK GOES
 * ============================================================================
 *
 * This matters more than any single page. A page added next year has to be able
 * to answer these four questions without asking anyone.
 *
 *   1. A MARK MUST NAME A RELATION THE LAYOUT CANNOT SHOW. Either it links two
 *      things standing apart (the thread), or it lifts the one fragment the
 *      reader is meant to carry away (the highlighter). A mark that merely
 *      decorates is forbidden. If you cannot say what the mark asserts, delete
 *      it.
 *
 *   2. MARKS FOLLOW DECISIONS, NOT LENGTH. A page that asks for a decision —
 *      home, a deck, pricing, a dead end — may carry marks. A page that informs
 *      — legal, support, a listing — carries none, however long it is. Length
 *      earns nothing.
 *
 *   3. A MARK NEVER RIDES INSIDE A LOOP. If the element is rendered N times
 *      (396 deck cards, five sample cards, ten support questions), the mark
 *      moves up to the page level or it goes. A mark multiplied by 396 is
 *      wallpaper, and wallpaper is the opposite of annotation.
 *
 *   4. ZERO MARKS IS NOT ZERO IDENTITY. The ink, the rule, the paper and the
 *      type carry the site everywhere. The trace is a supplement. A legal page
 *      with no mark on it must still be unmistakably this site — and it is,
 *      because rules 1 to 3 removed the mark, not the identity.
 *
 * WHAT THAT YIELDS, PAGE BY PAGE:
 *   home       3  highlighter on the promise · thread card→source · one underline
 *   deck page  1  the thread, and here it is literal: the sample card really did
 *                 come from the source named in the rights file
 *   pricing    1  highlighter on the word that decides — free
 *   article    0  rule 1, and this one was decided against. An underline wants
 *                 the sentence that answers the title, and the body is
 *                 author-written Markdown: the site cannot know which sentence
 *                 that is. A stroke placed by guess is decoration, and rule 1
 *                 forbids decoration. The reader annotates their own copy.
 *   404        1  the thread, pulled towards the way out
 *   listing    0  rule 3 — 396 cards, so the mark would be furniture
 *   support    0  rules 2 and 3 — it informs, and it loops over ten questions
 *   legal      0  rule 2 — nobody highlights a contract
 *   guides    0  rule 3
 *
 * ============================================================================
 * CONSTRAINTS, none of them negotiable
 * ============================================================================
 *
 *   1. NO REMOTE FONT, NO THIRD-PARTY SCRIPT, NO OFF-DOMAIN IMAGE. A privacy
 *      requirement (`CLAUDE.md`, "Vie privée"), enforced by NoThirdPartyTest.
 *      Every stroke below is drawn in CSS or inline SVG for that reason. There
 *      is no script on this site at all, including our own: the trace is
 *      scroll-driven CSS.
 *   2. LIGHT AND DARK, through `prefers-color-scheme`, like the app. The
 *      highlighter switches from `multiply` to `screen` — multiply on a dark
 *      ground turns to mud.
 *   3. NO HORIZONTAL SCROLL at 320 px. Wide things scroll inside their own
 *      container, never the page.
 *   4. NO SCRIPT FACE. Handwritten MARKS are SVG paths with uneven control
 *      points; handwritten WORDS are the system font, small, angled. A note
 *      reads as a hand because of where it sits, never because of a fake
 *      cursive.
 *
 * Colour, spacing and the type scale come from `tokens.css`, which mirrors the
 * Flutter app. A hard-coded colour here would drift the first time a token
 * moves.
