   songbook.css — the playing surface
   -----------------------------------------------------------------------------
   Chrome is built against the ratified taste corpus (records/skills/taste:
   color-type-layout.md standing laws + control-surfaces-spec.md), because the
   first pass invented its own conventions and hit four NEVERs:

     · bordered-rect control groups  → "a table in word" (e-08). Now: tight
       clusters, hairline separators, no boxes around controls.
     · dotted underline on the editable chord name → blueprint semantics belong
       to containers, never editable text (e-07). Now: a spine mark.
     · ghost buttons in control rows (e-06/07). Now: filled accent primary,
       tint-well secondary, ink third.
     · filled-pill chips rank LAST (e-06). Now: spine-chips, square r2.
     · didactic empty-state prose → "i hate text that tries to TEACH me"
       (YOU-SAID, STRONG, e-13). Now: empty states show the SHAPE of what will
       be there, and no string in this file instructs.

   Ambient constants: r2 corners (2px) · 3px uniform spine as the accent
   language · accent carries STATE, never surface · small-caps labels · mono
   tabular numerals · shell/dense spacing (clusters pad 9 / gap 7) · elevation
   present (blur-12 @ 20%) on floating surfaces only.

   The chart geometry below the chrome is unchanged: the horizontal axis is
   musical time, bars are equal grid columns, notation owns the vertical space
   and lyrics sit underneath. Density shrinks text and gaps, never notation.
