/* Tasks & Assessments — light-theme restoration.
   The family shell (tetra-kairos-skin.css + tasks-assessments-family.css) is a
   dark composition that paints content surfaces with opaque `!important` rules.
   Those pages were authored light, so under the light portal theme the dark
   paints clobber the authored design and the page reads as forced-dark.
   This layer re-asserts the authored light surfaces, scoped strictly to
   :root[data-tetra-theme="light"], so dark/obsidian are untouched. Load it
   AFTER the skin and family sheet. */
