/* controls.css — The job form: select, chips, segmented control, cards, custom printer.
   Cascade position 12 of 18. Order is load-bearing and is asserted by
   verify-fixtures.mjs; index.html links these explicitly (never @import) because Caddy's
   try_files turns a missing file into a 200 text/html SPA shell.
   Owner after Step 1: section (g).

   Section (g) restyle, 2026-09-06. Items 74, 98, 99, 100, 101, 102, 104, 105, 106, 107,
   149 (styling half), 150. Three rules govern every block below and each is a measured
   number, not a preference (REFERENCE-STUDY §18):

     - Hover changes FILL and BORDER COLOUR and nothing else. No transform, no shadow
       growth, no border-WIDTH change — a width change reflows and item 100 is a reflow bug.
     - Every transition here is 120ms (--sn-dur-fast) with one easing. Nothing exceeds 200ms.
     - Elevation is one property. Every box below carries a real 1px `border` and NO
       `box-shadow` spread ring; the shipped file expressed the same hairline as
       `box-shadow: inset 0 0 0 1px`, which meant a selected state had to grow the ring to
       1.5px and therefore repainted a different box model on selection.

   `opacity` is never used to express a disabled state (DESIGN-SPEC §9). The shipped chip
   was `opacity: .4` on --sn-ink over --sn-surface-2, which composites to 3.6:1; it is now
   --sn-ink-mute on --sn-surface-1, which is 5.71:1. */

/* ══ Select — DESIGN-SPEC §4.9, item 102 ══════════════════════════════════════════════

   rule anywhere in the sheet, on four of the eight decisions the product asks for.

/* ══ Choice chips — items 98, 99 ══════════════════════════════════════════════════════
   A chip row rather than a <select> because the whole point of item 1 is that the SET is
   the information — a customer should see that their Ender-3 V3 offers exactly one
   diameter without opening a menu.

   MEASURED before: widths 65.7 / 89.0 / 65.6 / 65.8. The 23px bulge was the 10px
   `<small>ships with this</small>` rendered on the stock chip alone, so the row's rhythm
   depended on which chip happened to be stock. The row is now ONE grid row of equal 1fr
   tracks: every chip is the same width and, because a grid row stretches, the same
   height, whichever one carries the sub-label and whatever the viewport.

   DELIBERATE DEVIATION from REFERENCE-STUDY §7's 28px chip, recorded in COMPONENT-PLAN
   §2(g): our chips keep DESIGN-SPEC §4.11's 40px floor because item 99 requires a
   reserved sub-label line and §9 sets a 32px accessibility floor — a 28px chip cannot
   hold two lines. We take §7's grammar (no wrap, colour-only 120ms transition, one row),
   not its height. Second deviation: the selected chip is --sn-accent-tint with an accent
   border, not §7's inverted light-on-dark fill, because DESIGN-SPEC §2.4 reserves the
   accent as the only colour an ACTION may wear and a light chip would out-shout the
   Prepare button beneath it. */

/* ══ Proceed-anyway — item 74 ═════════════════════════════════════════════════════════
   Amber, never green, and never pre-ticked. The checkbox was the browser default: a
   white square measured 13 x 15 px on a black card, under every target minimum, and
   `accent-color` only ever colours the CHECKED state. It is now a 20 x 20 control in the
   app's own language inside a <label> whose whole card is the hit area (DESIGN-SPEC
   §4.20 + mocks/NOTES.md A4: the 32px target is met by the label, not by the input).

   MEASURED COLLISION, and it is why the selector below is `.adv__grp > .danger` rather
   than `.danger`: `css/slider.css` (section h, cascade position 13, i.e. AFTER this file)
   declares `.adv__grp > label, .adv__lbl { display: flex; gap: 6px; align-items: baseline }`
   for the slider value labels. `.danger` IS a `<label>` and IS a direct child of
   `.adv__grp`, so that rule turned this card into a FLEX row — at equal specificity and a
   later cascade position it won — and the checkbox became a flex item that shrank from
   its declared 20px to 15px (offsetWidth 15, first "track" 15px, gap 6px, all measured in
   the running page). That is also why the audit found a 13 x 15 UA box here rather than
   the 16px the shipped `.danger` asked for. `.adv__grp > .danger` is (0,2,0) against that
   rule's (0,1,1) and wins on specificity alone, in either cascade order. A contract line
   asks section (h) to narrow its selector; this rule is correct whether or not it does. */

/* ══ UI Quiet — the four steps (choice-steps lane, 23 Sep) ═══════════════════════════════
   DESIGN.md §4.1, §4.2, §5.1 (step row), §5.2 (option row). controls.css loads AFTER
   rail.css, and every rule that re-seats a `.step` box names #step1 / #step2 by id, so it
   wins on specificity as well as order. Tokens only.

   Structure (index.html): #step1 is the Model step, driven by js/steps.js as before.
   #step2 is the setup group the rest of the app flips idle / live / inert / collapsed; its
   own head is drawn only once it collapses on a result (the "your choices" fold). Inside
   its body, .qs-step × 3 are Printer, Material and What matters most, opened one at a time
