/*
 * ICE Tools
 *
 * Design read: utility pages for someone who arrived from a search query and
 * wants an answer in under five seconds. Quiet instrument-panel language.
 * Low layout variance, near-zero motion, higher density than the college site.
 *
 * The section deliberately drops the college chrome (see ToolsLayout) but
 * keeps the --ice-* semantic tokens, so both themes and the Playwright theme
 * audit continue to hold. No new colour is introduced anywhere in this file.
 *
 * Structure of every tool page, top to bottom:
 *   1. a two-line head that names the tool and nothing else
 *   2. the working panel, above the fold on a phone
 *   3. short explanatory prose for the reader who wants to check the answer
 *   4. a strip of the other tools

/* One line colour, quieter than the structural navy, for the 32 hub cards.
 *
 * The hub was drawing 41 identical edges — 2px `border-strong` on the frame,
 * on the rule between every shelf, on the table wrapper, and on all 32 cards.
 * Same width, same ink, same radius, so nothing on the page was emphasised and
 * the grid read as graph paper. The width stays 2px: the ruled box is the
 * section's whole aesthetic, and `tools-visual.spec.mjs` holds it. What moves
 * is the ink, so the frame and the shelf rules outrank the things inside them.
 *
 * Light only. Dark never had the problem this fixes — the graphite ramp
 * already collapses `border` and `border-strong` onto one low-contrast line —
 * and it cannot afford the fix either: on the dark theme a card's fill and the
 * frame's fill are the SAME #2B2D31, so the border is the only thing that
 * makes a card a card. Quieting it there dissolves the grid. The dark value is
 * therefore the structural line, unchanged, and stated rather than inherited
 * so the next person does not read the omission as an oversight. */

   the six labels that carry the whole structure of the page read as body copy
   and the desktop scale went 45px → 18px → 18px with nothing in between. This
   is the missing step: ~19px on a phone, 27px on a desktop.

   The floor is set by the h1 and not by the body text. `.tool-head h1` is

   the page title instead of ranking under it; the curve keeps the h2 near

/* ── Hub prose and the full-section table ─────────────────────────────
   Added 2026-08-21. The hub was 338 words with no table and nothing on it
   that said what Kaamko is, which made the most-linked page in the section
   the least quotable. Both blocks sat above the card shelves until
   2026-08-28 and now sit below them: see the note in the page itself for
   why the SEO argument never required the top of the document.

   The table is deliberately a real <table> and not a grid of divs: it is
   comparative data, it is read as such by assistive tech, and it is the
   shape a retrieval system can lift whole. It scrolls inside its own
   wrapper rather than widening the page — same contract as every other
   scrollable table in this section. */
