#538's Compact and Tiles header styles carried two glyph rules of their own:
a `transform var(--transition-smooth)` transition on every header button's
svg, and `.btn-settings:hover > svg { rotate(45deg) }`. #561 had meanwhile
dropped the global button rotate and moved the hover motion onto the glyphs
(gear turn, folder, Tiles squares) behind `(hover: hover)` and a
prefers-reduced-motion off switch. The #538 rules out-specified those
guarded rules (they reach the glyph through `html[data-header-stats]
.header-right`), so under the default Tiles style a reduced-motion user
still saw the gear turn, a touch tap left it stuck at 45deg, and the 0.2s
ease replaced #561's spring.
Both rules go; #538 keeps only its glyph sizes, and the guarded motion now
applies the same in all three header styles. The hover test scanned only
selectors naming .btn-icon-header, which is how this slipped through: it
now scans every rule that reaches a header glyph and pins the one spring
transition and the hover guard.

A global `.btn-icon-header:hover { transform: rotate(45deg) }`, meant for
the settings gear, turned every header icon button on hover, so the folder,
Tiles, Split and the rest swung their rounded hover background into a
diamond. Three buttons had already cancelled it one by one (the font-size
buttons, notifications, the sidebar toggle).
The rule is gone, and with it those three overrides. Hover motion now moves
the icon only:
- the settings gear's icon turns 45 degrees (one tooth, so it lands on the
same shape);
- the Tiles button's four squares spread apart, each toward its corner;
- the folder cross-fades to an open folder (a second drawing in its SVG,
`.icon-folder-closed` / `.icon-folder-open`);
- every other icon just takes the hover colour.
Pointer devices only (`@media (hover: hover)`, so a tap cannot leave an icon
stuck mid-motion), and the transitions are off under reduced motion.
Owner request: the Tiles and folder buttons "weirdly turn" on hover.
Checked live on a dark and a light skin (rest, mid, end frames). Pinned by
test/header-icon-hover.test.ts, mutation-checked five ways (the button
rotation back, the open drawing missing, the motion not hover-gated, a
square spreading toward the wrong corner, reduced motion keeping its
transition). Gate: 507 files, 9798 tests passed.
