/**
 * Roadmap timeline (sections/roadmap-timeline.liquid).
 *
 * A release calendar, not a changelog: the organising fact of each entry is
 * WHEN, so the period ("SEPTEMBER", "Q4 2026") is set in the heading face at
 * display scale. From tablet up it gets its own rail beside the spine -
 * milestone labels down the left, work on the right - and sticks while a
 * long entry scrolls past, so the reader always knows which chapter they are
 * in. On mobile the rail folds away and the period sits as a chapter mark
 * above its card, spine on the left.
 *
 * The spine is segmented per entry rather than one unbroken line: each entry
 * draws its own connector down to the next marker, so the line itself can
 * carry that entry's status - solid success behind shipped work, plain
 * through the current build, dashed ahead of plans. Read top to bottom it is
 * a progress bar through time.
 *
 * Markers and chips encode state without relying on colour alone: shipped is
 * a filled success node carrying a check (the chip repeats it); in progress
 * is a brand-ringed node with a slow breathing halo - the only ambient
 * motion on the page, because it is the one thing actually alive; planned is
 * a dashed hollow, an outline of something that does not exist yet.
 *
 * Entries are quiet outline cards (same bones as .preorder-batch) that lift
 * on hover; a small caret on the card's left edge points back at the
 * entry's own marker so card and node read as one object. Shipped entries
 * recede whole - they are history, not news - while the in-progress card
 * carries a faint brand cast: it is the entry people came to check.
 *
 * All colours are theme tokens or color-mix() tints of them, so dark mode
 * falls out of the token swap with no rules here.
