Eight bite-sized tasks for the visual baseline: shared/glyphs.ts module,
color-token & focus-ring CSS in popup and vault, .req-pill class, migration
of all ten required-marker sites and ten emoji glyph sites to the shared
constants, gating of the popout-to-tab button on !isInTab(), and a static
"esc to cancel" subtitle in fullscreen forms.
Each task pairs a failing test with a minimal implementation; ends with a
commit. Sets the visual language that phases 2-4 build on.
