peter ab873bbcaa feat(theme): R10 S2 — re-close the rem system (px-frozen labels/chrome -> rem)
The ~124 px-frozen text-[Npx] labels didn't track the Settings font-scale slider
while their rem-sized neighbours did. Add text-2xs (0.6875rem) / text-3xs
(0.625rem) font-size-ONLY tokens (no paired line-height -> matches the arbitrary
they replace, zero vertical-rhythm shift) and codemod every text-[Npx] to a rem
class (rare 8/9/12/13px -> rem arbitraries).

Also: --hdr-h 68px -> 4.25rem so header content clears the rem-sized pills at
scale 1.3 instead of sliding under; NavSidebar/SidePanel slot widths + their
icon/badge px sizes go rem so the rails keep pace with their (now-scaling)
labels; a w-24/h-[54px] thumb -> h-13.5 to preserve 16:9 at scale. Media
thumbnails, page-width caps and fixed container widths deliberately stay px.

Verified via getComputedStyle at scale 1.06/1.3: text-2xs 11.66->14.3px, header
clearance 72->88px, nav slot 246->302px — all scale proportionally.

// Two variants, now one implementation on the R8 popover platform: "header" opens below the pill
// (used on the landing page and the setup wizard) and "rail" is an icon-only button in the left
// nav's bottom cluster whose menu opens to the RIGHT, bottom-aligned. Both used to hand-roll their
// own anchoring, and the header one also opened on hover — dropped on purpose: the platform focuses
// the first item when a menu opens, so a hover-open would yank focus off whatever the user was doing.
