/* THE `ch` OF THE `g<n>` Y-GUTTER RESOLVES ON `.chart-panel`, so its `font-size` below is
   load-bearing LAYOUT and not typography, and this note lives outside the rule because a brace
   in a comment inside it truncates every naive `_rule()`-style parser (including this repo's).
   Without a font-size the panel inherits the BODY size and `ch` means the body's `ch`: measured
   on the built page, 16px gives 1ch = 10.08px while the 11.5px axis labels give 1ch = 7.23px, so
   a g5 gutter reserved 55.42px for a widest label of 30.84px. 24.58px, 44% of the gutter, wasted
   on EVERY card at EVERY width. At 320px that surplus was the difference between the x labels
   clearing each other by +4.9px (the pre-window live site) and OVERLAPPING by -3.9px, a WCAG
   1.4.10 reflow failure and a loss of information, not cosmetic tightness.
   It was first filed as a harmless rough edge on the reasoning that `ch` against a larger font
   only ever over-reserves. Over-reserving IS the defect: the gutter steals plot width from the
   axis it exists to align. Matching the label size makes each `<n>.5ch` mean what it says, and
   it stays comfortably wider than the text it reserves (5.5ch x 7.28 = 40.0px vs 30.84px). */
/* ---------- trend chart panel: y gutter + plot + x axis (SITE-TREND-AXES-1) ----------
   The chart had NO axes at all, which made it decoration: a reader could not tell whether the
   rise happened over a week or a year, nor what any price on it was. The glyphs are HTML rather
   than SVG <text> because the panel scales 806/320 = 2.519x at the 1120px container and ~1.0x on
   a phone, so any type inside the viewBox would be 2.5x oversized on a desktop.
   The GRID is what keeps the labels aligned to the picture: one row for the plot, one for the x
   axis, and the plot column is `minmax(0, 1fr)` — NOT `1fr` — because `1fr`'s auto minimum is the
   SVG's 320px intrinsic width, which overflows the page below ~390px. */

/* THE INTERIOR LABEL GOES when the plot cannot hold three of them, leaving first and last.
   MEASURED: the gap between two adjacent label TEXTS is `(plot - sum of label widths) / 2`,
   because the outer two are edge-pinned and the middle is centred (g5 at 320px: (196.17 -
   177.30)/2 = +9.4 measured +8.6; g9 at 320px: (167.19 - 177.30)/2 = -5.1 measured -5.9). So the
   no-overlap condition is simply `plot > total label text`, and the worst case is three
   year-bearing labels: the widest string `_x_labels` can emit is "24 Aug 2026" at 70.66px in
   this font (browser-measured), so 3 x 70.66 = 211.97px. The threshold is 215px, i.e. the
   measured worst case and not an eyeballed one -- an earlier 200px guess was BELOW it, which
   would have left a three-year-label axis (reachable when a short span crosses New Year, so
   first, middle and last all carry a year) overlapping on a 201-212px plot.
   With the middle gone, two labels need 2 x 70.66 = 141.3px and the narrowest plot the layout
   can produce at 320px is ~166px (g11), so the pair always clears.
   Text-to-text, NOT cell-to-cell: the grid cells touch at 0px by construction, so measuring the
   cell boxes says nothing about whether the writing collides -- that is what made this defect
   invisible to a media-query grep and to a first browser pass.

   measured in Chrome it was handing every chip `border: 1px solid rgba(255,255,255,0.08)` and
   `font-weight: 500` that nobody here chose. The selected chip was an accent fill inside a

   CHANGE is accent vs surface-3 at 7.68:1, a luminance inversion rather than a hue-only shift

   `--surface-3`, under 1.4.11's 3:1) and `--text-tertiary` for the chip text (3.45:1, under the
   4.5:1 floor at this size). Both of those were first written down against `--surface`, the
   panel BEHIND the chips rather than the chip itself; against the chip they are 1.54 and 3.45,
   and both conclusions hold.
   STATED RATHER THAN HIDDEN: the unselected chip's own fill against the page `--bg` is 1.42:1,
   so the chip BOUNDARY does not meet 1.4.11's 3:1. That is deliberate and defensible -- the
